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...)
