Move the Waveshare panels description into separate document, so they

But why do we need "panel-dpi"? Adding that requires changing a DT.
Can't you make the kernel handle these compatible strings as a
"panel-dpi" without the compatible?
I can, but wouldn't we then miss the more specific compatible strings in
the DT ?
compatible = "waveshare,13.3inch-panel", "panel-dpi";
^^^^^^^^^^^^^^^^^^^^^^^^^^
this ... would be removed. Do we want that ?
No, drop "panel-dpi". Or really, don't add it.
The other option would be to add the timings into panel-simple driver,
then we wouldn't have to change the bindings at all. Maybe that would be
preferable ?
Why can't the "panel-dpi" driver match to"waveshare,13.3inch-panel"?
It could, but then, if I am already patching that panel-simple driver, I
can also simply include the timings in it, just like many other panels do.
