omap: am33xx: enable gpio support
This patch uses the code in omap-common to support gpio modules 1-3 on am33xx based boards. It adds base address and register definitions, enables clocks to the modules, and enables building the common gpio code for CONFIG_AM33XX as well as CONFIG_OMAP Signed-off-by: Steve Sakoman <steve@sakoman.com>
