ASoC: fsl_xcvr: clear the channel status control memory

Browse Source 
[ Upstream commit 73b97d46dde64fa184d47865d4a532d818c3a007 ]

memset_io() writes memory byte by byte with __raw_writeb() on the arm
platform if the size is word. but XCVR data RAM memory can't be accessed
with byte address, so with memset_io() the channel status control memory
is not really cleared, use writel_relaxed() instead.
