Subject: [PATCH] ASoC: fsl_esai: Fix incorrect xDC field width of xCCR registers

The xDC field should have 5 bit width according to Reference Manual.
Thus this patch fixes it.

The patch was originally submitted by Aurelien BOUIN while in an
informal way. And he hasn't finished any re-submitting during the
past two weeks. Thus I create a new patch with his signed-off
included so as to fix the probelm as soon as possible, not sure
whether it's decent or not though.
