ASoC: rt5651: Allow specifying over-current threshold through a device-property
OVer-Current-Detection (OVCD) for the micbias current is used to detect
if an inserted jack is a headset or headphones (mic shorted to ground).
Some boards may need different values for the OVCD current threshold
because of a resistor on the board in serial with or parallel to the
jack mic contact.
This commit adds support for configuring the OCVD current threshold
through the "realtek,over-current-threshold-microamp" device-property.
Note this commit changes the default value from 600uA to 2000uA,
because testing has shown 600uA to be a poor default.
