Anas Nashif 00c4d32d42 x86: add Quark D2000 Interrupt Controller (MVIC)
This module is based on the standard Local APIC and IO APIC source modules.

This modules combines these modules into one source module that exports the
same APIs defined by the Local APIC and IO APIC header modules. These
routine have been adapted for the Quark D2000 Interrupt Controller which has
a cutdown implementation of the Local APIC & IO APIC register sets.

Dmitriy Korovkin f1420515a7 irq: Add flags to IRQ_CONNECT_STATIC() macro and irq_connect() function
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()

Dmitriy Korovkin 93b0ced44b Order hardware and device initialization
The initialization procedures need to be called in the
following order:
- basic hardware initialization;
- devices initialization;
- hardware clock initialization, that the kernel needs to
  run the kernel server.
This way, the board initialization routines is placed
to the pure_early_init level to make sure it runs first,
all device initialization procedures run at pure_init level,
so they are initialized early enough to be used for debugging
if needed. Hardware clock initialization is placed on
nano_early_init level to make sure hardware clock is initialized
just before the kernel server starts.

Adds the Kconfig option for selecting the Cortex-M systick timer.  This helps
pave the way for moving the Cortex-M systick timer into the drivers/ directory.

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 Now it is obsolete and is removed.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.

Updating global variable's name to follow a consistent naming convention.

Change accomplished with the following script:

   #!/bin/bash
   echo "Searching for ${1} to replace with ${2}"
   find ./ \( -name "*.[chs]" -o -name "sysgen.py" -o -name "*.kconf" \) \
            ! -path "./host/src/genIdt/*" \
            ! -path "*/outdir/*" | xargs sed -i 's/\b'${1}'\b/'${2}'/g';
