i2c: rcar: clear NO_RXDMA flag after resetting

Browse source 
[ Upstream commit fea6b5ebb71a2830b042e42de7ae255017ac3ce8 ]

We should allow RXDMA only if the reset was really successful, so clear
the flag after the reset call.

Fixes: 0e864b552b23 ("i2c: rcar: reset controller is mandatory for Gen3+")
