Remove GENERIC_GPIO config option

Browse Source 
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.

not care how it's implemented.)
That said, if the convention is supported on their platform, drivers should
use it when possible. Platforms must declare GENERIC_GPIO support in their
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
on GENERIC_GPIO. The GPIO calls are available, either as "real code" or as
optimized-away stubs, when drivers use the include file:
