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.

ALC5621/ALC5622/ALC5623 audio Codec



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>;

	};
