Input: egalax_ts - get gpio from devicetree
The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework and don't support this API anymore. The i.MX6q sabrelite platform equips an egalax touchscreen controller, and this platform already transfered to GENERIC_GPIO framework, to support this driver, we use a more generic way to get gpio. Add a return value checking for waking up the controller in the probe function, this guarantee only a workable device can pass init.
