[PATCH][next] ASoC: uniphier: remove redundant check of blk_id

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The check of blk_id == AUD_CLK_IO is redundant as it also being performed
in the following switch statement with the same return of -ENOTSUPP. Fix
this by removing the redundant comparison.
