gpio: devm_gpio_* support should not depend on GPIOLIB
Some architectures (e.g. blackfin) provide gpio API without requiring
GPIOLIB support (ARCH_WANT_OPTIONAL_GPIOLIB). devm_gpio_* functions
should also work for these architectures, since they do not really
depend on GPIOLIB.
Add a new option GPIO_DEVRES (enabled by default) to control the build
of devres.c. It also removes the empty version of devm_gpio_*
functions for !GENERIC_GPIO build from linux/gpio.h, and moves the
function declarations from asm-generic/gpio.h into linux/gpio.h.
