make dtbs_check:

arch/arm/boot/dts/r8a7740-armadillo800eva.dt.yaml: sound@fe1f0000: '#sound-dai-cells', 'clocks', 'power-domains' do not match any of the regexes: 'pinctrl-[0-9]+'

Fix this by documenting the missing properties. Update the example to match reality. While at it, improve the document title, and comment the various compatible values with the corresponding SoC names.
