[ARM] pxa: move pxa_gpio_mode() outside of generic gpio.c
Browse files Browse the repository at this point in the history
Looks like we have to live with pxa_gpio_mode() for a while, giving
its presence is actually making gpio.c not generic enough, let's
move it temporarily outside before it can be fully purged.
