Stefan Wahren 82f811bd2c dt-bindings: display: bcm2835: add optional property power-domains
The Raspberry Pi boards with BCM283x needs control of the power domains
to get display components running. DT schema warns us that it's used, but not
documented as a optional property:

hdmi@7e902000: 'power-domains' does not match any of the regexes: ...
