From: Marek Vasut <marex@denx.de>
[ Upstream commit 087698939f30d489e785d7df3e6aa5dce2487b39 ]
The DRC02 has no use for the on-SoM touchscreen controller, and the on-SoM touchscreen controller may not even be populated, which then results in error messages in kernel log. Disable the touchscreen controller in DT.
