ARM: dts: Fix erroneous ADS touchscreen polarities

stable inclusion
from stable-v5.10.186
commit 32134e7a0f218f30b89ba2d3ea29a637722ac507
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8J4KH

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=32134e7a0f218f30b89ba2d3ea29a637722ac507



--------------------------------

[ Upstream commit 4a672d50 ]

Several device tree files get the polarity of the pendown-gpios
wrong: this signal is active low. Fix up all incorrect flags, so
that operating systems can rely on the flag being correctly set.
