extcon: Allow compile test of GPIO consumers if !GPIOLIB
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.
If GPIOLIB=n and asm-generic/gpio.h is not used:
drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_detect_cable’:
drivers/extcon/extcon-usb-gpio.c:63: error: implicit declaration of function ‘gpiod_get_value_cansleep’
drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_probe’:
drivers/extcon/extcon-usb-gpio.c:116: error: implicit declaration of function ‘devm_gpiod_get’
drivers/extcon/extcon-usb-gpio.c:116: warning: assignment makes pointer from integer without a cast
drivers/extcon/extcon-usb-gpio.c:122: error: implicit declaration of function ‘gpiod_set_debounce’
drivers/extcon/extcon-usb-gpio.c:129: error: implicit declaration of function ‘gpiod_to_irq’
Add the missing #include <linux/gpio/consumer.h> to fix this.
