// *! DESCRIPTION : Revert MCS configuration applied by SBE (FAPI)
// *!
// *! OWNER NAME : Joe McGill Email: jmcgill@us.ibm.com
// *!
// *! ADDITIONAL COMMENTS:
// *!
// *! Disable MCS configuration written by SBE to enable initial phase of
// *! HBI execution (providing lpc_ack for dcbz prior to initialization
// *! of memory). Registers touched by SBE (MCFGP, MCIFIRMASK) will be
// *! reset to flush state by this procedure.
