ASoC: codec: realtek: Make the node name generic
"The name of a node should be somewhat generic, reflecting the function
of the device and not its precise programming model."

Do as suggested in the bindings examples.

RT5651 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "realtek,rt5651".
- reg : The I2C address of the device.
Optional properties:
- realtek,in2-differential
Boolean. Indicate MIC2 input are differential, rather than single-ended.
- realtek,dmic-en
Boolean. true if dmic is used.
- realtek,jack-detect-source
u32. Valid values:
1: Use JD1_1 pin for jack-detect
2: Use JD1_2 pin for jack-detect
3: Use JD2 pin for jack-detect
- realtek,over-current-threshold-microamp
u32, micbias over-current detection threshold in µA, valid values are
600, 1500 and 2000µA.
- realtek,over-current-scale-factor
u32, micbias over-current detection scale-factor, valid values are:
0: Scale current by 0.5
1: Scale current by 0.75
2: Scale current by 1.0
3: Scale current by 1.5
