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.

Used typically if GPIO is used for USB ID pin detection.
