gpio: drop unneeded Kconfig dependencies on OF_GPIO 

OF_GPIO is selected automatically on all OF systems. Any symbols it
controls also provide stubs so there's really no reason to select it
explicitly. Remove all Kconfig dependencies/selects for GPIO drivers.
For those that have no other dependencies: convert it to requiring
CONFIG_OF instead to avoid new symbols popping up in make config.
