The reset gpio logic of the atmel driver was changed to be active low at
around the same time this device tree was accepted into the kernel.
Adjust the configuration so that the touchscreen is in a usable state.

Please use proper subsystem prefix in the title, so "ARM: dts: exynos:".
Also capitalize names (Atmel) and acronyms (GPIO, not
gpio).
Thanks, applied.
Best regards,
Krzysztof
