[PATCH v2 1/1] dt-bindings: fsl: fsl,rcpm: Add #power-domain-cells

[Alexander Stein]

dtbs_check for ls1021.dtsi warns about unsupported property:
 power-controller at 1ee2140 (fsl,ls1021a-rcpm): '#power-domain-cells' does not match any of the regexes: '^pinctrl-[0-9]+$'

But if removed the check warns about missing property:
 power-controller at 1ee2140 (fsl,ls1021a-rcpm): '#power-domain-cells' is a required property

Given commit 8bcf67b8d893b ("ARM: dts: ls1021a: add #power-domain-cells
for power-controller node") explicitly added that property, add it
to the expected property list as well.

Fixes: ad21e3840a88 ("dt-bindings: soc: fsl: Convert rcpm to yaml format")
