Rename node name power-controler to wakeup-controller because it is not
power controller and enable/disable a wakeup source.

Add remove #power-domain-cells.

Fix below CHECK_DTBS warnings:
  arch/arm/boot/dts/nxp/ls/ls1021a-tqmls1021a-mbls1021a-rgb-cdtech-fc21.dtb: power-controller@1ee2140 (fsl,ls1021a-rcpm): '#power-domain-cells' does not match any of the regexes: '^pinctrl-[0-9]+$'
	from schema $id: http://devicetree.org/schemas/soc/fsl/fsl,rcpm.yaml#
