Laura Abbott 97fe7bef56 gpio: Remove VLA from stmpe driver ...

The new challenge is to remove VLAs from the kernel
(see https://lkml.org/lkml/2018/3/7/621)

The number of GPIOs on the supported chips is fairly small
so stack allocate to a known upper bound and spit out a warning
if any new chips have more gpios.
