ASoC: omap-mcbsp: Fix FS polarity for LEFT_J, DSP_A and DSP_B formats
Commit 75d9ac4 ("ASoC: Allow DAI formats to be specified in the dai_link") changed DAI format flag values and we cannot simply invert anymore e.g. frame-sync with ^= SND_SOC_DAIFMT_NB_IF (which was anyway misuse) as there is no anymore fixed bit position for bit-clock or frame-sync inversion. Fix this by relying only on DAI format flag values passed to us and by not making any assumption on individual bit positions.
