configure Cumulus MC inband logic to pass host/occ bit under BAR
In p9 mode, MCMODE0 bit 25 controls the extent of the inband BAR match:
- bit 25 = 0b0 -- BAR match down to RA bit 38
- bit 25 = 0b1 -- BAR match down to RA bit 37, bit 38 passed to Centaur
indicating host or OCC access
In p8, we used the host/OCC bit to indicate the requestor. Current
OCC code is continuing this behavior, so we need to set MCMODE0 bit 25
to allow this.
