Remove GENERIC_GPIO config option 



GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus
safe to have GENERIC_GPIO removed.

That said, if the convention is supported on their platform, drivers should

Kconfig (boolean true), and provide an <asm/gpio.h> file.  Drivers that can't

work without standard GPIO calls should have Kconfig entries which depend
