ASoC: renesas: msiof: use reset controller

Browse source

MSIOF has TXRST/RXRST to reset FIFO, but it shouldn't be used during SYNC
signal was asserted, because it will be cause of HW issue.

When MSIOF is used as Sound driver, this driver is assuming it is used as
clock consumer mode (= Codec is clock provider). This means, it can't
control SYNC signal by itself.

We need to use SW reset (= reset_control_xxx()) instead of TXRST/RXRST.
