[PATCH v2] dt-bindings: mxsfb: Document i.MX8M power-domains property

[Marek Vasut]

The power-domains property is mandatory on i.MX8M Mini, Nano, Plus.
Document the property and mark it as required on the aforementioned
variants of the IP, present in those SoCs.

Please mention both i.MX6sl and i.MX6sx SoCs in the patch subject and
commit message.

As I mentioned in v1 review comment, please add '- fsl,imx6sl-lcdif'
here too?
