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.
