[ Upstream commit bd540ebe68c3017194a1caa38e075bbbc0832749 ]
Add the board level fixed regulators for 3.3V and 1.8V which is used to power - among other things - the tlv320aic3106 codec.
Apart from removing the following warning during boot: tlv320aic3x-codec 0-0018: Invalid supply voltage(s) AVDD: -22, DVDD: -22
With the correct voltages the driver can select correct OCMV value to reduce pop noise.
