ARM: dts: da850-lcdk: Correct the audio codec regulators
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.
