Different VIA host bridges use different offsets to their AGP config
registers, so add a register offset array to the softc. We key off the
device ID to determine which set of register offsets. Currently the 8385
host bridge used on amd64 is the only bridge to use the AGP3_VIA_*
register offsets and all other bridges use the AGP_VIA_* offsets. It is
currently unclear if the AGP3_VIA_* offsets are for VIA bridges that
implement AGP 3.0 bridges or just for amd64 bridges.
