dt-bindings: mfd: rk817: Fixup clocks and reference dai-common

Ensure 'clocks' property does not allow more than one item and add the
missing reference to dai-common schema.

While at it, move 'clocks*' and '#sound-dai-cells' properties to keep
the list ordered alphabetically.

Additionally, drop all useless/redundant descriptions.
