[PATCH] ASoC: tlv320aic3x: Fix data delay configuration

[Peter Ujfalusi]

Fix the issue introduced by:
368494093354 ASoC: tlv320aic3x: Add TDM support

The CTRLC register were not receiving the correct delay configuration,
which will corrupt DSP_A audio mode.

Hi,

most of my boards are using DSP_B or I2S mode... This is why this is slipped.

Please put "Fixes:" tag in such a case.

I guess we'll have a chance to send the last pull request for 3.19 in
the next week.  If we miss it, we'll have to mark this with Cc to
