Add a kernel timer driver for the MEC1501 32KHz RTOS timer.
This timer is a count down 32-bit counter clocked at a fixed
32768 Hz. It features one-shot, auto-reload, and halt count down
while the Cortex-M is halted by JTAG/SWD. This driver is based
on the new Intel local APIC driver. The driver was tuned for
accuracy at small sleep values. Added a work-around for RTOS
timer restart issue. RTOS timer driver requires board ticks per
second to be 32768 if tickless operation is configured.

Have the SoC dtsi files for microchip mark the devices (uart & i2c) as
disabled by default and let the board dts files enable which one's they
need/use (which is what's happening already).

Dts Nodes for all the GPIO portswere defined. In addition,
a new binding file was created for the gpio driver.

Initial support for Microchip MEC1501 series is added to the tree.
Additional support for UART is also included. This SoC supports
two operational modes for interrupts (Direct and Aggregated). For
this commit, the direct capable interrupts are configured in
direct mode.
