Initialization priority value for each platform is defined
in the platform Kconfig file.
Drivers and platform code use SYS_DEFINE_DEVICE to add

Move the files that *know* about the calling convention in use by the
compiler. The routines exposed by the files moved to the i386_sysV_abi
directory follow the C calling convention specified by the
i386_sysV_abi which is the default for GCC. The upstream GCC has been
enhanced to support the iamcu_ABI that is optimized for processors
that implement the IA MCU instruction set. This new ABI provides code,
data and stack size improvements on IA MCU based systems.
This change is the first step in adding support for the IA MCU
optimized toolchains to Zephyr OS

When building for a certain platform, we have no idea
what architecture we are building for.
We used to specify the architecture alongside the board or platform
name and this was used to find the defconfig in arch/<arch>/configs.
By putting all board configurations we support in one place we do
not have to specify the architecture, just the configuration name.

and some gcc options did not work with clang. Move those to be conditional
on the compiler used to make clang work.
To build with clang for x86:
make CC=clang -C samples/microkernel/apps/hello_world/
You still need the gcc cross environment for various tools.
For now, only x86 was tested.

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()
