ASoC: rockchip: Add machine driver for RK3399 GRU Boards

Because we need to support the multiple codecs (MAX98357A/RT5514/DA7219)
on the RK3399 GRU boards, this patch can help us to support these codecs.

ROCKCHIP with MAX98357A/RT5514/DA7219 codecs on GRU boards
Required properties:
- compatible: "rockchip,rk3399-gru-sound"
- rockchip,cpu: The phandle of the Rockchip I2S controller that's
connected to the codecs
- rockchip,codec: The phandle of the MAX98357A/RT5514/DA7219 codecs
Example:
sound {
compatible = "rockchip,rk3399-gru-sound";
rockchip,cpu = <&i2s0>;
rockchip,codec = <&max98357a &rt5514 &da7219>;
};
