ASoC: qcom: q6apm-lpass-dais: add TDM DAI operations

Browse source

Add TDM DAI operations to q6apm-lpass-dais so AudioReach TDM
backends can be configured through the normal ASoC hw_params and DAI
setup flow.

The TDM set_tdm_slot() callback validates the supported slot width and
slot count, stores the active slot mask in the AudioReach module
configuration, and leaves existing DMA, I2S and HDMI paths unchanged.

Reuse the existing LPASS child-clock handling for TDM nodes as well as
MI2S nodes, since TDM backends also request optional backend clocks
through the machine driver set_sysclk() path.
