Use new scratch reg for hb_done and set early in IPL
This is to support using the scratch register for the power off
message. I moved to a new scratch register since we were sharing
with a SBE scratch reg that was needed early in HB IPL.
NOTE! This will have a co-req with an FSP track so we'll need to
coordinate.
