arm64: dts: rockchip: Add HDMI audio outputs for rk3588

For hdmi0_sound, use the simple-audio-card driver with the hdmi0 QP node
as CODEC and the i2s5 device as CPU.

Similarly for hdmi1_sound, the CODEC is the hdmi1 node and the CPU is
i2s6, but only added in the rk3588-extra.dtsi device tree as the second
TX HDMI port is not available on base versions of the SoC.

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 and hdmi1 nodes so
that they can be used as audio codec nodes.
