Andrew Lunn 7d6d478f38 ASoC: alc5623: Add device tree binding
Let the ALC5623 codec be instantiated from DT. Add a simple binding
for the additional control register and the jack detect register.

Also, add a prompt to the Kconfig entry for this CODEC, so that it can
be selected. Since kirkwood-t5325.c will no longer be used, we need to
be able to enable the CODEC in the mvebu_v5_defconfig etc.

Required properties:
- compatible: "realtek,alc5623"
- reg: the I2C address of the device.
Optional properties:
- add-ctrl: Default register value for Reg-40h, Additional Control
Register. If absent or has the value of 0, the
register is untouched.
- jack-det-ctrl: Default register value for Reg-5Ah, Jack Detect
Control Register. If absent or has value 0, the
register is untouched.
Example:
alc5621: alc5621@1a {
compatible = "alc5621";
reg = <0x1a>;
add-ctrl = <0x3700>;
jack-det-ctrl = <0x4810>;
};
