Update the binding and pinctrl-zynqmp driver to add Versal platform
support.
Add Get Attribute ID in the Xilinx/AMD firmware driver to get the pin
information from Xilinx/AMD Platform Management Firmware.

Changes in v2:
-> 1/3 - Created new binding doc for Versal platform (suggested by Rob).
-> 1/3 - Update regex for pins properties to make sure it always starts
         with "LPD" or "PMC" string.
-> 3/3 - Used firmware API to get platform information to differentiate
         platform specific code (suggested by Jay).
