dt-bindings: display: simple-framebuffer: Add panel-dimensions property

Commit fbf0ea2 ("of: property: fw_devlink: Add a devlink for panel
followers") added a probe ordering hint. This is not necessary for
simple-framebuffer which is expected to be left in an useable state by
the bootloader. simpledrm uses the panel property only to query the
physical dimensions. Add panel-dimensions property which comes without
probe ordering. simpledrm will parse both properties.
