24x7: Update of P9 proc config to HOMER.

24x7 application needs a unit availability vector populated
in HOMER. This unit availability vector should represent
functional state of various chiplets of P9 chip. This vector
needs to be populated  during IPL time and subsequently
during runtime periodically.
