Input: atmel_mxt_ts - allow reset GPIO to sleep

Browse Source 
commit c7866ee0a9ddd9789faadf58cdac6abd7aabf045 upstream.

The reset GPIO is not toggled in any critical section where it couldn't
sleep, allow the reset GPIO to sleep. This allows the driver to operate
reset GPIOs connected to I2C GPIO expanders.
