Hmm, then opb (On-chip Peripheral Bus) is better?

I agree that files.ibm405gp should be merged into files.ibm4xx,
but it may require:
- options IBM405GP (or something) is needed to specify ibm405gp.c
(or should it be renamed to obppci.c??)
- declaration of rtc.c should be conditional by kernel config
