taiko audio CODEC

Required properties:

  - compatible : "qcom,taiko-slim-pgd"
  - elemental-addr: codec slimbus slave PGD enumeration address.(48 bits)

  - qcom,cdc-reset-gpio: gpio used for codec SOC reset.

  - <supply-name>-supply: phandle to the regulator device tree node
  - qcom,<supply-name>-voltage -  specifies voltage levels for supply. Should be
       specified in pairs (min, max), units mV.
  - qcom,<supply-name>-current - specifies max current in mA that can drawn
       from the <supply-name>.

    above three properties with "supply-name" set to  "qcom,cdc-vdd-buck", "qcom,cdc-vdd-tx-h",
     "qcom,cdc-vdd-rx-h", "qcom,cdc-vddpx-1", "qcom,cdc-vdd-a-1p2v", "qcom,cdc-vddcx-1",

 - qcom,cdc-micbias-cfilt2-mv - cfilt2 output voltage in milli volts.

   This value represents the connected CFLIT to MIC Bias.
