There are 2 other timers that could be selected, let's just take the
first 32bits one. This should be sufficient to verify the driver.
Enabling the timer in relevant board's dts file as well.

Such basic timer is found on MEC150x for instance.
Since instances have dedicated data, let's define specifice instance
based on unique DT base address definition.

Configuration item custom busy wait is required for all MEC1501
series if its RTOS timer driver is enabled. We moved the selection
of the timer from board level to MEC1501 SoC level.
Frequency selection remains at the board level.

This is required to get the watchdog test and sample working since the
required wdt device name macro is generic there.

Use address based defines in the dts_fixup.h instead of DT_INST_ based
ones. The DT_INST_ will not get us the consistent mapping that is
needed (as we should assume the order of DT_INST_).

Changes to MEC1501 HAL for eSPI changed loop constant used by SoC
code initializing the ECIA registers. Fixed by using HAL constants
that are invariant.

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).

and gpio functionality are located in the same PCR register
for each pin.
Introduce pinmux Kconfig switches for the SOC.

In kernel_arch_init() we initialize the ARM core (interrupt
setup, fault init, etc.) so we can also move z_clearfaults()
in the same function and skip invoking it in the SoC init
functions.

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 interrupt are configured in direct
mode.
