ASoC: qcom: q6dsp: Add Senary MI2S audio interface support

Browse source 
Backport of the Senary MI2S port support merged upstream in 7.2-rc1
(series "ASoC: qcom: q6dsp: few fixes and enhancements"), using the
same port IDs (SENARY_MI2S_RX=147/TX=148; 137-146 are reserved for the
upstream LPI MI2S ports) so device trees remain compatible across the
rebase. Needed for the Fairphone (Gen. 6) speaker amplifiers, which sit
on Senary MI2S.
