ARM: dts: exynos: switch Atmel mxt reset GPIO to active low on P4 Note

Browse Source 
The reset GPIO logic of the Atmel maxtouch driver was changed to be
active low at around the same time P4 Note device tree was accepted into
the kernel.  Adjust the configuration so that the touchscreen is in a
usable state.
