55fdd1fd33 device: Provide generic API to handle synchronous calls in drivers
Introduce the device_sync_call_t object type and its API.

This object type allows one thread to perform synchronous calls into a
driver. Only one thread can do such calls per instance of the
device_sync_call_t object since it makes a global record of what type of
thread is waiting on it.

Based on an idea from Dmitriy Korovkin and Peter Mitsis, moving their
proposal to a more generic API provides the solution for all device
drivers that exposes synchronous API in an interrupt based
implementation.

a894799c94 arc: static IRQ handling
Adds support for static IRQ handler initialization.

Currently, IRQ_CONNECT and IRQ_CONFIG macros are emulating static
behavior through dynamic initialization.
This commit updates the macros to get real static initialization.
IRQ handlers must be assigned at build time.

1d816afcc0 serial: remove unused code after refactoring
Remove unused code after refactoring all the serial/UART drivers.

() Since device initialization is done by the drivers themselves,
   there is no need to have config_func(), port_init() and uart_init()
   to perform configuration external to driver. So remove the related
   bits.
() The IRQ priority is only being used when doing IRQ_CONNECT_STATIC().
   So there is no need to send it over during uart_init().

bba9510319 irq_offload: API to run a function in IRQ context
Software interrupts or system calls aren't really appropriate for
zephyr, but we have an ongoing need in our test code to run a
function with arguments synchronously in interrupt context.

This patch introduces irq_offload() which allows us to do this without
separate initialization or having to manage fake IRQs in the
interrupt controller.

ARM assembly code contributed by Benjamin Walsh
<benjamin.walsh@windriver.com>

ARC is not yet implemented but will be in a subsequent patch.

irq_test_common.h has been removed and all test cases updated to
use the new API.
