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.

Say Y here to enable GPIO based USB cable detection extcon support.
Used typically if GPIO is used for USB ID pin detection.
