ASoC: rcar: clear DE bit only in PDMACHCR when it stops
[ Upstream commit 62a10498afb27370ec6018e9d802b74850fd8d9a ]
R-Car datasheet indicates "Clear DE in PDMACHCR" for transfer stop,
but current code clears all bits in PDMACHCR.
Because of this, DE bit might never been cleared,
and it causes CMD overflow. This patch fixes this issue.
