arm64: dts: rockchip: Drop invalid mic-in-differential on rk3568-rock-3a

The 'mic-in-differential' DT property supported by the RK809/RK817 audio
codec driver is actually valid if prefixed with 'rockchip,':

  DTC_CHK arch/arm64/boot/dts/rockchip/rk3568-rock-3a.dtb
  rk3568-rock-3a.dtb: pmic@20: codec: 'mic-in-differential' does not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: http://devicetree.org/schemas/mfd/rockchip,rk809.yaml#

However, the board doesn't make use of differential signaling, hence
drop the incorrect property and the now unnecessary 'codec' node.
