ARM: dts: Fix erroneous ADS touchscreen polarities 



[ Upstream commit 4a672d500bfd6bb87092c33d5a2572c3d0a1cf83 ]

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.
