This patch set is to add support for Audio over wcd codec,
digital mics, through digital codecs and without ADSP.

Changes Since V5:
    -- Include MI2S primary node to snd_soc_dai_driver in lpass-sc7280 platform driver.
    -- Move dependency patch list to corresponding patch.
    -- Add support for missing cdc-dma ports.
    -- Change if/else conditional statements to switch cases.
    -- Add missing error handlings.
    -- Typo errors fix.
Changes Since V4:
    -- Remove unused variable in lpass-sc7280 platform driver.
Changes Since V3:
    -- Remove redundant power domain controls. As power domains can be configured from dtsi.
Changes Since V2:
    -- Split lpass sc7280 cpu driver patch and create regmap config patch.
    -- Create patches based on latest kernel tip.
    -- Add helper function to get dma control and lpaif handle.
    -- Remove unused variables.
Changes Since V1:
    -- Typo errors fix
    -- CPU driver readable/writable apis optimization.
    -- Add Missing config patch
    -- Add Common api for repeated dmactl initialization.
