调试HDMI音频能8通道播放声音

一、使用场景

我们是通过rk主控的hdmi接口播放音视频给到ite68051芯片解析出8声道数据，分别通过4路i2s的数据脚给给到fpga去解析

调试步骤：

1.根据相关手册配置hdmi输出，hdmi声卡注册，如下:

hdmi0_sound: hdmi0-sound {
        status = "disabled";
        compatible = "rockchip,hdmi";
        rockchip,mclk-fs = <128>;
        rockchip,card-name = "rockchip-hdmi0";
        rockchip,cpu = <&i2s5_8ch>;
        rockchip,codec = <&hdmi0>;
        rockchip,jack-det;
    };

&hdmi0_sound {
    status = "okay";
};

&i2s5_8ch {
    status = "okay";
};

hdmi0: hdmi@fde80000 {
        compatible = "rockchip,rk3588-dw-hdmi";
        reg = <0x0 0xfde80000 0x
