[PATCH RESEND v6 2/3] arm64: dts: rockchip: Add HDMI0 audio output for rk3588 SoC

[Detlev Casanova]

Use the simple-audio-card driver with the hdmi0 QP node as CODEC and
the i2s5 device as CPU.

The simple-audio-card,mclk-fs value is set to 128 as it is done in
the downstream driver.

The #sound-dai-cells value is set to 0 in the hdmi0 node so that it can be
used as an audio codec node.
