audio-lnx: Propagate changes from kernel for msm_sdw/hdmi

Add snapshot for msm_sdw codec/hdmi codec drivers for SDM targets.
The code is migrated from msm-4.9 kernel at the below cutoff -

(8efe4a8d64f: "ARM: dts: msm: add rotator vbif memtype
		setting to sdm845")

This changes are done to migrate msm_sdw/hdmi codec drivers
to this new audio kernel techpack.
