Use the gpios instead of gpio suffix that is mandated by the binding.
This dtbs_check warning is fixed now:
  touchscreen@5c: Unevaluated properties are not allowed ('reset-gpio' was unexpected)
The reset signal worked correctly as both the "gpio" and "gpios" suffixes
are actually allowed by the gpiolib.
