Add documentation to describe Xilinx ZynqMP firmware driver
bindings. Firmware driver provides an interface to firmware
APIs. Interface APIs can be used by any driver to communicate
to PMUFW (Platform Management Unit).

+
+The zynqmp-firmware node describes the interface to platform firmware.
+
+Required properties:
+ - compatible: Must contain:  "xlnx,zynqmp-firmware"
+ - method:     The method of calling the PM-API firmware layer.
+               Permitted values are:
+                - "smc" : To be used in configurations without a hypervisor
+                - "hvc" : To be used when hypervisor is present
+
+Examples:
+       zynqmp_firmware: zynqmp-firmware {
+               compatible = "xlnx,zynqmp-firmware";
+               method = "smc";
+       };
