Support HB running in SMF
Support SMF for P9N/P9C. Lots of minor tweaks to make this
work, but the biggest is to run userspace in problem state
This is needed because for SMF Hostboot will need to run in S=1,
HV=0,PR=1 (and kernel in S=1, HV=1, PR=0)
This commit makes P9 HB userpsace run in HV=0 PR=1 and kernel in
HV=1, PR=0.
