ASoC: wm8962: Make the node name generic
According to Devicetree Specification v0.2 document:

"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 binding example.

WM8962 audio CODEC
This device supports I2C only.
Required properties:
- compatible : "wlf,wm8962"
- reg : the I2C address of the device.
Optional properties:
- spk-mono: This is a boolean property. If present, the SPK_MONO bit
of R51 (Class D Control 2) gets set, indicating that the speaker is
in mono mode.
- mic-cfg : Default register value for R48 (Additional Control 4).
If absent, the default should be the register default.
- gpio-cfg : A list of GPIO configuration register values. The list must
be 6 entries long. If absent, no configuration of these registers is
performed. And note that only the value within [0x0, 0xffff] is valid.
Any other value is regarded as setting the GPIO register by its reset
value 0x0.
Example:
wm8962: codec@1a {
compatible = "wlf,wm8962";
reg = <0x1a>;
gpio-cfg = <
0x0000 /* 0:Default */
0x0000 /* 1:Default */
0x0013 /* 2:FN_DMICCLK */
0x0000 /* 3:Default */
0x8014 /* 4:FN_DMICCDAT */
0x0000 /* 5:Default */
>;
};
