arm64: dts: rockchip: Drop invalid clock-names from es8388 codec nodes

The binding for Everest ES8328/ES8388 audio CODEC doesn't support the
'clock-names' property:

  rk3588-orangepi-5-plus.dtb: audio-codec@11: 'clock-names' does not match any of the regexes: 'pinctrl-[0-9]+'
    from schema $id: http://devicetree.org/schemas/sound/everest,es8328.yaml#



Since the related audio driver is also not making use of it, drop the
invalid property from all es8388 codec nodes.
