asm/gpio.h is included only by linux/gpio.h, and then only when the arch
selects ARCH_HAVE_CUSTOM_GPIO_H. Only the following arches select it: arm
avr32 blackfin m68k (COLDFIRE only) sh unicore32.
Remove the unused asm/gpio.h files for the arches that do not select
ARCH_HAVE_CUSTOM_GPIO_H.
This is a follow-on to 7563bbf89d06 ("gpiolib/arches: Centralise
bolierplate asm/gpio.h").

Rather than requiring architectures that use gpiolib but don't have any
need to define anything custom to copy an asm/gpio.h provide a Kconfig
symbol which architectures must select in order to include gpio.h and
for other architectures just provide the trivial implementation directly.
This makes it much easier to do gpiolib updates and is also a step towards
making gpiolib APIs available on every architecture.
For architectures with existing boilerplate code leave a stub header in
place which warns on direct inclusion of asm/gpio.h and includes
linux/gpio.h to catch code that's doing this. Direct inclusion of
asm/gpio.h has long been deprecated.
