Socionext EVEA - UniPhier SoC internal codec driver

Required properties:
- compatible : should be "socionext,uniphier-evea".
- reg : offset and length of the register set for the device.
- clock-names : should include following entries:
"evea", "exiv"
- clocks : a list of phandle, should contain an entry for each
entries in clock-names.
- reset-names : should include following entries:
"evea", "exiv", "adamv"
- resets : a list of phandle, should contain reset entries of
reset-names.
- #sound-dai-cells: should be 1.

Example:

codec {
compatible = "socionext,uniphier-evea";
reg = <0x57900000 0x1000>;
clock-names = "evea", "exiv";
clocks = <&sys_clk 41>, <&sys_clk 42>;
reset-names = "evea", "exiv", "adamv";
resets = <&sys_rst 41>, <&sys_rst 42>, <&adamv_rst 0>;
#sound-dai-cells = <1>;
};
