This patch extends the i2c shim driver so it supports the 'default

default configuration for the I2C device. The default configuration
is set during driver initialization.
This patch also changes Quark SE and D2000 Kconfig.defconfig files so
the i2c default configuration is set to '0x12' which means standard
bus speed, 7-bit addressing and master mode. This is the same value
used when DW driver is selected, by the way.

This patch fixes the gpio, i2c and watchdog shim drivers so they set the
CLK_PERIPH_CLK bit during driver initialization. Differently from Quark
SE, the peripheral clock gate bit (CLK_PERIPH_CLK) is not enabled by
default in Quark D2000. We have to explicitly set this bit in order to
properly initialize the device.
This issue has been masked so far because the CLK_PERIPH_CLK bit is set
when UART NS16550 driver is enabled. The UART NS16550 driver is enabled
by default for Quark D2000 so gpio, i2c and watchdog sample apps were
working just fine. But if we disable the NS16550 driver, these samples
applications stop working.
The remaining shim drivers already set the CLK_PERIPH_CLK bit during
initialization so there is no need to fix them.

Due to an issue with the interrupt-based transfer API from QMSI driver,
the 'transfer' callback from the shim driver (i2c_qmsi_transfer) is
implemented with polling APIs. This is not ideal because we are not able
to sleep the current thread (so another task can be scheduled in) while
the i2c operation is carried out.
The interrupt issue with the QMSI driver has been solved then this patch
fixes the shim driver so it uses the interrupt-based API and adds extra
code to handle the thread synchronization.
Finally, this patch also moves all 'struct device' related definitions
from the bottom to the top of the i2c_qmsi.c file so the DEVICE_GET
macro can be used in transfer_complete() and removes the init.h include
since it is not needed anymore.

This patch introduces the QMSI I2C driver which is simply a shim driver
based on I2C driver provided by QMSI BSP.
This initial version supports only I2C_0 controller in 'master' mode.
Due to some issues with qm_i2c_master_irq_transfer API, the driver uses
the polling APIs from QMSI. This means that the current thread doesn't
sleep (i.e. is not scheduled out) while the I2C transfer is carried out.
The qm_i2c_master_irq_transfer() issue is under investigation.
Below follows the missing features which will be addressed by a new
version of this patch or by upcoming patches.
* Block the current thread until the I2C operation has actually
completed.
* Add support for multiple controllers.
* Add support for slave mode.
* Add support for suspend() and resume() APIs.
In order to enable this driver, the following options should be set:
CONFIG_QMSI_DRIVERS=y
CONFIG_QMSI_INSTALL_PATH="/path/to/libqmsi/directory"
CONFIG_I2C=y
CONFIG_I2C_QMSI=y
Finally, due to the lack of proper support for Quark SE in QMSI 1.0.0,
this driver requires QMSI version greater than 1.0.0.
This driver has been tested only with Quark SE based boards.

The interrupt API has been redesigned:
- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
It will be used in situations where the new static irq_connect()
won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
exactly the same way as its dynamic counterpart. The old static irq
macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
generated inline with irq_connect()
ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

not standalone. Use a more descriptive name and remove the architecture

Put initialization priorities as device driver Kconfig
parameter.
Initialization priority value for each platform is defined
in the platform Kconfig file.
Drivers and platform code use SYS_DEFINE_DEVICE to add
and initialization function.

Do not depend on environment variables and use a kconfig variable
for defining the architecture.
In addition, remove the X86_32 variable, it just duplicates X86 for
not good reason, at least until start supporting MCUs with 64bit.

This adds the I2C driver for the Sensor Subsystem on Quark SE.
This provides minimal support for the I2C controller, and does
only synchronous transfer at the moment.

Flags allow passing IRQ triggering option for x86 architecture.
Each platform defines flags for a particular device and then
device driver uses them when registers the interrupt handler.
The change in API means that device drivers and sample
applications need to use the new API.
IRQ triggering configuration is now handled by device drivers
by using flags passed to interrupt registering API:
IRQ_CONNECT_STATIC() or irq_connect()

Add a context value to the ioapic and loapic mkstub macros to allow
the developer to specify a context value that will be passed on the
stack to the interrupt service routines.
All the invocations for the loapic_mkstub and ioapic_mkstub macros
have been changed to pass in 0 so there is no functional difference
ATM. This change removes the need for drivers to have trampoline ISR
routines to pass a context vaule to their generic ISR routine.
This is the first step in getting rid of the hack where the driver
needs to look into the __initconfig_* linker objects.

Gets rid of the trailing initialization level character from the
name of the device variable generated by the macro, since it serves
no useful purpose. (The linker scripts place the various initialization
sections in ascending order based on the name of the section, so there
is no need to embed the initialization level in the variable name itself.)

With the introduction of generic transfer function, it is no longer
needed to specify read or write functions explicitly in drivers.
All read/write functions can now thus call the generic transfer
function to achieve the same result.
With this change, the transfer function becomes mandatory, and
should always be available.
