Input: atmel_mxt_ts - improve T19 GPIO keys handling
* The mapping of the GPIO numbers into the T19 status byte varies between
different maXTouch chips. Some have up to 7 GPIOs. Allowing a keycode array
of up to 8 items is simpler and more generic. So replace #define with
configurable number of keys which also allows the removal of is_tp.
* Rename platform data parameters to include "t19" to prevent confusion with
T15 key array.
* Probe aborts early on when pdata is NULL, so no need to check.
* Move "int i" to beginning of function (mixed declarations and code)
* Use API calls rather than __set_bit()
* Remove unused dev variable.
