ALSA: ASoC: tlv320aic3x: Fix DSP DAI format and signal polarities matching

Browse source 
- Codec doesn't support to configure bit clock and frame sync polarities
- Codec doesn't support DSP_A format but DSP_B with inverted bit clock
  polarity
- Match also other formats with their signal polarities
