Dirk Brandewie 147d6585ae x86: arm: Modify IRQ_CONFIG macro to have same signature as ARC
In order to have drivers that are usable cross architecture the
signature for IRQ_CONFIG needs to be the same to avoid #ifdef hell in
the driver code based on architecture.

Update the macro and it usage for existing drivers

Fixes the SYS_CLOCK_HW_CYCLES_PER_SEC Kconfig option dependencies such that
it can be overridden by a modified platform configuration file.  This is
particularly important for the LOAPIC timer driver as
SYS_CLOCK_HW_CYCLES_PER_SEC is dependent upon the target's CPU/bus frequency.

Dmitriy Korovkin 8d065343c2 Use static interrupt registration in device drivers
Make device drivers use static interrupt registration procedure.

DYNAMIC_INT_STUBS configuration parameter was used only by device
drivers to switch between static and dynamic interrupt registration
procedures. Now it is obsolete and is removed.

uart_int_connect() function is removed. If UART device driver still
needs to register interrupt dynamically, it should use
irq_connect(uart_irq_get()).

Dmitriy Korovkin 660878e4e2 irq_connect for x86 uses static stub array
In order to provide the same irq_connect() on all platforms
on x86, irq_connect() now uses a static array of interrupt
stubs. Device driver does not need to provide interrupt stub
to irq_connect() function.

Add NUM_DYNAMIC_STUBS configuration parameter, the number
of interrupt stubs used for dynamic interrupt registration.

Modify tests for unified interrupt register API

Tests that deal with interrupts are modified to work
with the new interrupt registration API.

Add CONFIG_NUM_DYNAMIC_STUBS option to dynamic interrupt projects

Projects that use dynamic interrupt handler registration on x86
have to include CONFIG_NUM_DYNAMIC_STUBS parameter in the
configuration.

Dmitriy Korovkin 6dd108a263 IRQ_CONNECT_STATIC implementation for x86 platform
In order to simplify x86 interrupt stub creation, each interrupt
controller implements an interrupt stub definition macro.

Add IRQ_CONNECT_STATIC() for static interrupt registration, and
construct the interrupt stubs name from device and interrupt
handler names.

Add IRQ_CONFIG() macro for the interrupt controller configuration.
On x86 platform it programs APIC to associate an IRQ number with
the interupt vector.

Add HPET_TIMER0_INT_PRI parameter to Quark platform header to
make it build correctly.
