[PATCH v2 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.

Changes in v2:
 - Move static variable to inside zynqmp_pmufw_node and change name to
   skip_config from config_enabled
 - Use zynqmp_pmufw_node() in zynqmp_power_probe() to check for APU_0
   config loading instead of calling zynqmp_pmufw_load_config_object()
