Input: bu21013_ts - convert to use GPIO descriptors
This driver can use GPIO descriptors rather than GPIO numbers without any problems, convert it. Name the field variables after the actual pins on the chip rather than the "reset" and "touch" names from the devicetree bindings that are vaguely inaccurate. No in-tree users pass GPIO numbers in platform data so drop this. Descriptor tables can be used to get these GPIOs from a board file if need be.
