xilinx: firmware: Introduce zynqmp_pmufw_node() for loading PMU fragments

Introduce zynqmp_pmufw_node() for loading PMU configuration fragment for
enabling IPs. Firmware driver has small overlay where NODE id is added and
config fragment is sent to PMUFW. There is a need to build PMUFW with
fragment support.
