MEC172X has 2 package sizes with additional pins on the -LJ package.
This commit separates the package-specific parts into different files.
In addition, this patch removes unnecessary package-specific enums in
favor of calculated offsets into the desired registers.

Fix Microchip XEC clock control driver single-ended XTAL2 pin
initialization. Add support for external 32KHZ_IN pin as a
clock source including PINTRL to switch the GPIO to 32KHZ_IN
function. Add device tree option to disable internal silicon
oscillator if it is not required by the configuration. Add
device tree tuning options based on crystal and board layout.

Microchip MEC172x has a modified eSPI SAF hardware implementation.
Hardware changes include multiple clock dividers for each SPI
flash device and data transfer using QMSPI local DMA.
espi reset interrupt is made a higer priority in MEC172x devicetree
because espi reset event resets all espi hardware and we don't
to want to service any other espi interrupt blocks when espi reset
occurs.

Microchip MEC172x QMSPI expanded its clock divider register
field from 8 to 16 bits. QMSPI source clock is on the fast
peripheral domain therefore get the frequency from the clock
control driver.

In order to bring consistency in-tree, migrate all soc code to the
new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

Correct eSPI flash macro so it not always results in zero,
leading to eSPI flash read operation in all cases:
Read, write, erase.

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.

Consensus was reached to locate Microchip MEC172x header files
in the zephyr MEC172x SoC folders. These are the first set of
headers specific to MEC172x and common to the MEC family. Hardware
register structures will be located in peripheral specific headers.
Update based on latest merge of MEC172x related files.
