The IRQ triggering condition should be specified by SoC as it is
a decision for hardware design. This should not be configurable
in kconfig.
The default is to be triggered on rising edge, just as the same
old kconfig did.

Moves those kconfig options which should be declared in
SoC or board header files instead. These are the one
that are tied to SoC or board and there is no need
for them to be configurable in kconfig.

Most of the SoC and board Kconfig use the same values for
driver initialization priorities. So refactor them, and
discard duplicate ones.
The shared IRQ init priority was changed so that the kernel
default init and device init priorities can be standardized
across all SoC/boards. Same goes for DesignWare SPI driver.
This also changes the UART_CONSOLE_PRIORITY and
IPM_CONSOLE_PRIORITY to UART_CONSOLE_INIT_PRIORITY and
IPM_CONSOLE_INIT_PRIORITY, to standardize across all drivers.
Note that this does not take away the ability to override
those values. This just provides reasonable defaults such
that there is virtually no need to override.

This adds conditions to the default values for device init priorities,
and make them follow the dependencies on the config options. This cleans
up the resulting .config a bit, making it easier to read.

There are two major issues with the kconfig:
() Some of the config options have incorrect dependencies inside help
under menuconfig. For example, CONFIG_GPIO depends on BOARD_GALILEO.
() Since the SoC and board specific kconfig files are parsed first,
the help screen would say, for example, CONFIG_SPI is defined at
arch/arm/soc/fsl_frdm_k64f/Kconfig. This is incorrect because
the actual config is defined in drivers/spi/Kconfig.
These cause great confusion to users of menuconfig/xconfig.
To fix these, the SoC and board defaults are now to be parsed last.
Note that the position swapping of defaults in this patch is due to
the fact the the default parsed last will be used.
And, spi_test is broken due to the fact that it requires
CONFIG_SPI_INTEL_PORT_1, but never enables it anywhere. This is
bypassed for now.

These options should be selected by individual SoC automatically,
and should not be visible options. Or else it would be possible to
select Quark SoCs and telling Kconfig it is from Atom family (which
is incorrect).

The peripherals utilizing UART were required to register their own
ISR rountines. This means that all those peripherals drivers need
to know which IRQ line is attached to a UART controller, and all
the other config values required to register a ISR. This causes
scalibility issue as every board and peripherals have to define
those values.
Another reason for this patch is to support virtual serial ports.
Virtual serial ports do not have physical interrupt lines to
attach, and thus would not work.
This patch adds a simple callback mechanism, which calls a function
when UART interrupts are triggered. The low level plumbing still needs
to be done by the peripheral drivers, as these drivers may need to
access low level capability of UART to function correctly. This simply
moves the interrupt setup into the UART drivers themselves. By doing
this, the peripheral drivers do not need to know all the config values
to properly setup the interrupts and attaching the ISR. One drawback
is that this adds to the interrupt latency.
Note that this patch breaks backward compatibility in terms of
setting up interrupt for UART controller. How to use UART is still
the same.
This also addresses the following issues:
() UART driver for Atmel SAM3 currently does not support interrupts.
So remove the code from vector table. This will be updated when
there is interrupt support for the driver.
() Corrected some config options for Stellaris UART driver.
This was tested with samples/shell on Arduino 101, and on QEMU
(Cortex-M3 and x86).

Decisions on compiler optimizations were done on the architecture level,
this does not scale and some SoCs will have different optimization levels
or compiler options needed. Moving this to the SoC makes it easy to optimize
differently when using the same CPU which we use to set the right optimization
now on the architecture level.

IRQAGENT3 is initialized explicitly, but IRQAGENT0 isn't and its value
is based on the value the BIOS or bootloader had set before. Fix this by
explicitly initializing IRQAGENT0, and swizzle the IRQs to reduce
conflicts.
Update the pci_pin2irq function to accommodate for these changes.
Also remove pci_irq2pin function since it is unused.
