This goes the safe route of adding a match for the P4P800 that does not
match the P4P800-E Deluxe which is already in. It seems quite likely that
the whole P4P800 family could use the same board enable with one generic
board enable match, though.
This match uses host bridge + audio, because all other IDs match the
P4P800-E Deluxe board, as reported in
