[PATCH 5.10 023/120] ARM: dts: stm32: Disable optional TSC2004 on DRC02 board

[Greg Kroah-Hartman]

From: Marek Vasut <marex at 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.
