ASoC: fsl-asoc-card: Add some improvements

Shengjiu Wang <shengjiu.wang@nxp.com> says:

This patch series addresses several issues in the Freescale Generic ASoC
Sound Card driver related to hardware limitations, DPCM path switching,
and codec-specific constraints.

The fsl-asoc-card driver provides a generic machine driver for i.MX SoCs,
supporting various codecs and optional ASRC (Asynchronous Sample Rate
Converter) for sample rate conversion. During testing several issues were
identified:

1. Missing channel constraint propagation in DPCM mode
2. DPCM path switching causing audio dropouts
3. Hardware channel alignment requirements
4. Clock generation limitations preventing certain audio formats
5. Codec-specific PLL frequency violations
