Enable PM Malf Alert Handling & PM Complex FFDC to HOMER

1. Enable ATTR_PM_MALF_ALERT_ENABLE so that alerts due to a PM
   Complex failure are sent to PHYP and related callouts, etc by PRD
   are enabled. This is enabled only for PHYP loads.
2. Enable ATTR_PM_RESET_FFDC_ENABLE so that on a PM Complex Reset
   triggered due to PM Errors (e.g. Malf alert, etc.), PM Complex FFDC
   is captured and stored in the HOMER to enable debug.
