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

- 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 Signed-off-by: Jarkko Nikula <jarkko.nikula@nokia.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
