[PATCH 13/15] OMAP: GPIO: cleanup _set_gpio_wakeup(), remove ifdefs

Make _set_gpio_wakeup() generic by removing ifdefs. Code for the
various SoCs/bank-methods was already the same, except for the
non-wakeup GPIO checking. But that flag is set on a per-SoC basis, so
can be used for all SoCs.
While here, use pr_err() and remove GPIO bank calculation assumption
based on subtracting bank pointers.
