Scott Cheloha 1621563ec6 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.
