description:
The TC device addresses are defined in KSEG1, but this confuses
bus_space(9) which expects bus addresses and not kernel virtual
addresses. Pull the addresses back to bus addresses with
MIPS_KSEG1_TO_PHYS().
XXX: Fix this properly one day (without storing KSEG1 addrs in
the TC device configuration).
Fixes problem with TURBOchannel pmaxes panicing during
autoconfiguartion.
