[PATCH 1/3] input: touchscreen: edt-ft5x06: make wakeup source behavior configurable

[Daniel Mack]

Allow configuring the device as wakeup source through device properties, as
not all platforms want to wake up on touch screen activity.

Note that by default, the device will now no longer be a wakeup source.
