'arm,rtsm-display' is a panel for Arm, Ltd. virtual platforms (e.g. FVP). The binding has been in use for a long time, but was never documented.

Some users and an example have a 'panel-dpi' compatible, but that's not needed without a 'panel-timing' node which none of the users have since commit 928faf5e3e8d ("arm64: dts: fvp: Remove panel timings"). The example does have a 'panel-timing' node, but it should not for the same reasons the node was removed in the dts files. So update the example in arm,pl11x.yaml to match the schema.
