They're not calling gpiochip_add afaik so they should really only select
GENERIC_GPIO.

The problem here is that gpio_request_one has been added to the ads7846
driver but gpio_request_one is not defined in GENERIC_GPIO case (I
guess that other (arm and non-arm) platforms may hit similar troubles
with gpio_request_one. One quick fix would be to add a gpio_request_one
function say in asm-generic/gpio.h. One other fix would be to define
gpio_request_one and gpio_request_array in each
machine/platform/... specific header. Don't know what's the best
solution.
