ARM: OMAP: 5912 OSK GPIO updates
Start cleaning up GPIO handling for OMAP5912 OSK board:
- Initialize GPIOs using the cross-platform calls, not the old
OMAP-private ones.
- Move touchscreen setup out of ads7846 code into board-specfic
setup code, where it belongs.
This doesn't depend on the patches to update OMAP to use the
gpiolib implementation framework.
