description:
Fix wdsc(4) probe failure on HPC1.5 machines (Indigo R3k/R4k, IP6/IP10/IP12).

The alignment adjustment code was removed in rev 1.36 for common
mips bus_space changes, but the code was not bus_space related
but used for uint32_t register acccess during probe.

Reported and tested by Naruaki Etomi in PR port-sgimips/53522.
Should be pulled up to netbsd-8.
