There is a fair amount of warnings when running 'make dtbs_check' with
amlogic,gx-sound-card.yaml.
Ex:
arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0:1: missing phandle tag in 0
arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0:2: missing phandle tag in 0
arch/arm64/boot/dts/amlogic/meson-gxm-q200.dt.yaml: sound: dai-link-0:sound-dai:0: [66, 0, 0] is too long
The reason is that the sound-dai phandle provided has cells, and in such
case the schema should use 'phandle-array' instead of 'phandle'.
