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. Signed-off-by: Scott Worley <scott.worley@microchip.com>
