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.
