[RFC 4/4] hack: arm64: dts: imx8mq-librem5: add purism, panel-librem5-workaround

[Martin Kepplinger]

From: Martin Kepplinger <martin.kepplin...@puri.sm>

Until we have a better solution, we need the touchscreen driver to
wait for the panel to be prepared, before it can continue to
execute probe().

A better driver is needed, so this is marked as a hack.
