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.
