[PATCH 2/5] firmware: zynqmp: Load config overlay for core0 to pmufw

[Ashok Reddy Soma]

Try loading pmufw config overlay for core0, if it doesn't return any
error it means pmufw is accepting nodes for other IP's. Otherwise dont
try to load config object for any other IP, just return from
zynqmp_pmufw_node function.
