Daniel Leung fed1cc8833 x86: galileo: pinmux: update get/set functions
This implements the get function for the Galileo pinmux
driver. Also modify the set function so that the get
function would work correctly.

Dirk Brandewie ad5af93f25 x86: Add context value to loapic_mkstub and ioapic_mkstub macros
Add a context value to the ioapic and loapic mkstub macros to allow
the developer to specify a context value that will be passed on the
stack to the interrupt service routines.

All the invocations for the loapic_mkstub and ioapic_mkstub macros
have been changed to pass in 0 so there is no functional difference
ATM.  This change removes the need for drivers to have trampoline ISR
routines to pass a context vaule to their generic ISR routine.

This is the first step in getting rid of the hack where the driver
needs to look into the __initconfig_* linker objects.

Allan Stephens a860cb7bff init: Support fine-grained device initialization priorities
Introduces the SYS_DEFINE_DEVICE() macro, which supports 5 distinct
levels of device initialization and 100 priorities within each level.

Note: The existing init macros (e.g. nano_early_init()) have been
adapted to utilize the enhanced initialization model, but will
eventually be retired.

Peter Mitsis 5705d06874 x86: Properly initialize _interrupt_vectors_allocated[] bitmap
Updates the 'gen_idt' tool to generate a bitmap of (statically) allocated
interrupt vectors that is linked into the final image in a manner similar to
the static IDT. The kernel then uses this bitmap when dynamically connecting
an interrupt vector, thereby preventing the dynamic irq connections
from clobbering the static irq connections.

Dirk Brandewie 002c53b225 drivers: add shared interrupt driver
This driver allows multiple drivers to share a common interrupt
line. This functionality is required on system that conform to the PC
interrupt structure.  In the context of Zephyr this is needed for
SOC's that have their I/O IP blocks behind a PCI interface. Due to the
limited number of interrupt lines provided by the PCI interface
multiple IP blocks may be configured to share an interrupt line.

Drivers that share interrupts  must be modified to *not* register their
own interrupt service routine as part of their configuration/initialization
but instead bind to the correct instance of this driver by name, then
register their interrupt service routine with this driver.
