omap drivers: switch to standard GPIO calls
This updates most of the OMAP drivers which are in mainline to switch to using the cross-platform GPIO calls instead of the older OMAP-specific ones. This is all fairly brainless/obvious stuff. Probably the most interesting bit is to observe that the omap-keypad code seems to now have a portable core that could work with non-OMAP matrix keypads. (That would improve with hardware IRQ debouncing enabled, of course...)
