In the high system load situation, bus latency increase was observed
and it made impact to other feature (e.g. audio dropouts). This is
because some modules push as much as possible traffic into the DBSC4
CAM for execution, and make increasing bus latency. Re-defining swap
priorities reduce this situation. This advice has been confirmed by
hardware developer.

Pull out the PRR_* macros into rcar_def.h and remove multiple copies of
it. Now that there are still RCAR_* macros in rcar_def.h too and they
have the exact same meaning as the PRR_* macros, but that's for another
patch.
