ASoC: tas2764: Fix and extend FSYNC polarity handling Fix setting of FSYNC polarity in case of LEFT_J and DSP_A/B formats. Do NOT set the SCFG field as was previously done, because that is not correct and is also in conflict with the "ASI1 Source" control which sets the same SCFG field! Also add support for explicit polarity inversion.
