powerpc/pseries: add FW_FEATURE_WATCHDOG flag
PAPR v2.12 specifies a new optional function set, "hcall-watchdog", for the /rtas/ibm,hypertas-functions property. The presence of this function set indicates support for the H_WATCHDOG hypercall. Check for this function set and, if present, set the new FW_FEATURE_WATCHDOG flag.
