gpio/omap: consolidate direction, input, output, remove #ifdefs
Add register offset fields to GPIO platform_data for registers. This patch adds registers that control direction, input and output data. Using these register offsets in the common driver allows removal of #ifdefs and greatly improves readability. Also create dedicated data out functions: one for banks with dedicated set/clear registers, and another for banks with a single mask register. Signed-off-by: Kevin Hilman <khilman@ti.com>
