feat(rcar3): change CAM setting to improve bus latency of R-Car Gen3 

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.
