gpiolib: fix up function prototypes etc
Commit 69e1601bca88809dc118abd1becb02c15a02ec71 "gpiolib: provide provision to register pin ranges" Got most of it's function prototypes wrong, so fix this up by: - Moving the void declarations into static inlines in <linux/gpio.h> (previously the actual prototypes were declared here...) - Declare the gpiochip_add_pin_range() and gpiochip_remove_pin_ranges() functions in <asm-generic/gpio.h> together with the pin range struct declaration itself. - Actually only implement these very functions in gpiolib.c if CONFIG_PINCTRL is set. - Additionally export the symbols since modules will need to be able to do this.
