'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.

The Arm PL110 and PL111 are IP blocks that provide a display engine with
an LCD interface, being able to drive a variety of LC panels.

Convert the binding over to DT schema, to the DTs can be automatically
checked.
This still contains the deprecated "arm,pl11x,tft-r0g0b0-pads" property,
because this is used by several DTs in the tree.
