i2c: rcar: fix resume by always initializing registers before transfer

commit ae481cc139658e89eb3ea671dd00b67bd87f01a3 upstream.

Resume failed because of uninitialized registers. Instead of adding a
resume callback, we simply initialize registers before every transfer.
This lightweight change is more robust and will keep us safe if we ever
need support for power domains or dynamic frequency changes.
