[PATCH] GPIO API: PXA wrapper cleanup
Based on the discussion last december (http://lkml.org/lkml/2006/12/20/242),
this patch:
- moves the PXA_LAST_GPIO check into pxa_gpio_mode
- fixes comment and includes in gpio.h
- replaces the gpio_set/get_value macros with inline
functions and adds a non-inline version to avoid
code explosion when gpio is not a constant.
