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.

The PIT is an unsupported device. On x86 based platforms, the LOAPIC_TIMER and
HPET_TIMER are the only supported timers.

Creating the LOAPIC timer Kconfig options permits future commits to remove
those settings from the relevant board.h files.
NOTE: No defconfig files have been modified as the LOAPIC_TIMER configuration
option is not enabled in any of them.

Adds additional Kconfig options to the HPET timer for setting its base address,
IRQ, IRQ priority and condition for triggering an interrupt.

The name of the device is SYSTICK. The device name should be part of the
file name, like all other timer drivers we support. The name
'cortex_m_timer' said nothing about which device the driver is for, since
it's way too generic: it could be for any timer present on any Cortex-M
board.

Qemu implements HPET so that it is connected to IRQ 2, which makes
necessary to use it in legacy emulation mode.
Add legacy emulation mode to HPET driver.
Change the way the HPET driver is initialized. QEMU requires that
the mode (one shot or periodic) gets set prior loading comparator
value.
Add debugging mode to HPET driver to ease the next port.

Updates the timer driver dependencies to simplify the selection of a timer
driver. The timer driver menu only lists those drivers that are compatible
with the previously selected interrupt controller.

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.

This commit standardize the Kconfig inclusion.
Selective sourcing of Kconfig files create conflict when merging
different configuration files (.config files).
Instead, now each kconfig symbols is dependant of its specific
DRV_* driver ksymbol.
