[ Upstream commit a0572c0734e4926ac51a31f97c12f752e1cdc7c8 ]
The uSD card detect signal on the DH DRC02 is active-high, with
a default pull down resistor on the board. Invert the polarity.

Note that this could not be tested on prototype SoMs, now that it is
tested, this issue surfaced, so it needs to be fixed.

[ 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.

[ Upstream commit 83d411224025ac1baab981e3d2f5d29e7761541d ]
The GPIO hog flags are ignored by gpiolib-of.c now, set the flags to 0.
Since GPIO_ACTIVE_HIGH is defined as 0, this change only increases the
correctness of the DT.
