In order to restore watchdog context after entering
SYS_PM_DEEP_SLEEP, suspend and resume functions
are called.
The following parameters are restored:
- All registers for the WDT device.
- Watchdog interrupt mask.
The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

Uses locking in an API and removes a global variable
for improved safety/correctness in the face of concurrent
threads and fibers.
The locking mechanism is by default disabled in the
build. To enable it, the following flag needs to be defined:
CONFIG_WDT_QMSI_API_REENTRANCY

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.

This patch replaces all occurences of the macro DEV_OK by the actual
value 0 at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

It's not a function and requires all its arguments to be build-time
constants. Make this more obvious to the end user to ease confusion.

This is the last step before obsoleting DEVICE_DEFINE() and
DEVICE_INIT_CONFIG_DEFINE().

Rename them to DEVICE_NAME_GET and DEVICE_GET to fit in the 'device'
namespace.

Rename it to DEVICE_DEFINE() so that it fits in the 'device' namespace.

Rename it to DEVICE_INIT_CONFIG_DEFINE(), because (a) it was not fitting
in any namespace and (b) it is not used to declare, but rather define a
object.

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.

This patch introduces the QMSI watchdog driver which is simply a shim
driver based on watchdog driver provided by QMSI BSP. This driver has
been tested with the latest version of QMSI BSP (1.0.0).
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_WATCHDOG=y
CONFIG_WDT_QMSI=y
