ALSA: ASoC: OMAP: Continue fixing DSP DAI format in McBSP DAI driver

Fix "ASoC: OMAP: Fix DSP DAI format in McBSP DAI driver" was not correct
due misunderstanding of DSP_A format and similar error in TLV320AIC33
codec which was used to test the original fix.

This patch corrects now DSP_A format in OMAP McBSP DAI driver and is
verified with TLV320AIC23 codec that's implementing DSP_A correctly.
