Microchip MEC172x series I2C driver implementing controller
and target modes. The driver implemenents its own I2C port
pin control functions and does not depended upon pinmux. Future
updates will make use of PINCTRL when that subystem is finalized.

Microchip XEC has been using the standard NS16550 driver.
Using the standard NS16550 driver requires extra HW programming
for XEC UART in board level and did not support XEC GIRQ interrupt
programming. We add an XEC specific driver and remove UART specific
register programming from the board level and implement interrupt
support. Also, by implementing a SoC specific driver we can add
driver PM in the future.

Update the Microchip XEC pinmux driver to use system I/O
routine for read/write of registers instead of direct use
of volatile and CMSIS defines. Add GPIO port number to
bindings instead of using hard coded value from chip headers.
Modify SoC DTSI pinmux syntax, requires "pinmux: pinumx {..."
or the DT macros will not work. Since pinmux is used by MEC152x
we update its chip pinmux DT.

Create version 2 of the MEC GPIO driver to support MEC172x to not
interfere with MEC152x. When the MEC172x ECIA interrupt aggregator
driver is ready, this driver will use ECIA for registering GPIO
interrupt callbacks instead of maintaining its own interrupt table.
Add V2 DT binding.
Add the Kconfig configuration settings for the MEC172x GPIO
V2 driver at the SoC and board level.
Add port id to DT allowing use of DT FOR EACH macro in the driver.

Update Microchip XEC RTOS timer driver adding MEC172x support and
using more device tree properities in the driver. We must also update
the XEC counter driver to use the new GIRQ DT properties.
Add new properties to RTOS timer and RTC timer YAML. These two timers
are linked due to option using a high speed timer for kernel busy wait.
Add Kconfig logic for XEC RTOS timer to MEC172x SoC.
Enable the Microchip XEC RTOS timer in the MEC172x evaluation board.
Add device tree nodes for most peripeherals.

Add driver implementation and header files for a MEC172x
aggregated interrupt driver. Enable the parent(ECIA) node
to have the driver initialize interrupt hardware for use.
Enable child nodes for those GIRQs used for aggregation.
Refer to chip documention for the list of GIRQs restricted
to aggregation and those which support direct mode.
Add chip level device tree node for MEC172x EC interrupt
aggregator parent and GIRQ children. Each child node contains
a list of sources representing the source bit position in the
GIRQ registers.
Add DT bindings for ECIA and GIRQ nodes.
Add build file(s) and configuration items for the MEC172x ECIA
aggregated interrupt driver. Add and enable the MEC172x interrupt
driver on the MEC172x evaluation board(EVB). Enable parent node to
initialize ECIA hardware. Child nodes are left disabled until a
future driver needs them.

Implement a clock control driver for Microchip MEC172x handling
configuring the 32 KHz input sources for the PLL and peripheral-32k
clock domains. MEC172x differs from MEC152x. MEC152x had one 32K source
for both PLL and peripherals. MEC172x allows the two domains to use
independent 32 KHz sources. Device tree updated to provide addresses
of hardware used by the driver.
