Run LPC Init to clean up errors on MPIPL
Recently HBBL added some error checking on LPC accesses
Unfortunately OPAL leaves some errors in the accumulated
status register of the LPC Host Controller.
Since HBBL doesn't have the space to clear... have the
SBE run lpc_init on MPIPL to clean up
Keep a global alias for HRMOR Attribute in Pibmem
Fetch the SPMode from Default SPMODE Attr if Mbox8 valid bit is
not set, else fetch it from Mbox3 bit3.
This is to support BMC scratch register setting which are all NULL
