Add girq and girq-bit to encode per device information. This allows the
driver to get any device unique info from device tree.

The I2C controllers on the MEC1501 SoC can be attached to
different I2C output line. For example, the I2C #0 controller
can be used with I2C7 physical lines out of SoC. The output
selection is done by the attribute "port_sel". This renames
the parent I2C nodes on the SoC side to refer to
the controller themselves instead of the output lines to
avoid confusion. The labels of these nodes are also renamed
to reflect the controllers.
On the board level, the DTS labels are overwritten to indicate
the actual output lines.
Aliases are also provided in both SoC and board levels to
provide shortcuts to the DTS nodes.

4 are found: 2 with a counter of 16bits and 2 with a counter of 32 bits.
However, first 32bits instance will not be exposed as it will be used by
rtos timer driver directly to implement k_busy_wait()

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).

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.
