pinctrl: pinctrl-zynqmp: Add support for Versal platform

Add Pinctrl support for Xilinx Versal platform.
Driver checks for firmware support to retrieve the Pin information, if it
is supported then proceed further otherwise it returns error saying
operation not supported. Latest Xilinx Platform Management Firmware must
be used to make use of the Pinctrl driver for Versal platform.
