The current convention seems to be that the "family" is set by the
service processor type since it's different for each generation of
FSP. The current specs suggests that ibm,p9 should be the family type
for the P9 FSP machines with BMC machines being something else
entirely.

I've got a patch to set these from the family and type fields they
added to the IPL params, I'll post it as a reply.
