These patches are to support audio over DP port on Qualcomm's SC7180 LPASS
Asoc. It includes machine driver, cpu driver, platform driver updates for

optimization and configuration changes.
These patches depends on the DP patch series

Changes Since v4:
    -- Updated with single compatible node for both I2S and HDMI.
Changes Since v3:
    -- Removed id in lpass variant structure and used snd_soc_dai_driver id.
Changes Since v2:
