[PATCH 01/27] drm/bridge: ptn3460: #include <linux/gpio/consumer.h>, depend on GPIOLIB

[Geert Uytterhoeven]

If GPIOLIB=n and asm-generic/gpio.h is not used:

    drivers/gpu/drm/bridge/ptn3460.c: In function ‘ptn3460_pre_enable’:
    drivers/gpu/drm/bridge/ptn3460.c:135: error: implicit declaration of function ‘gpiod_set_value’
    drivers/gpu/drm/bridge/ptn3460.c: In function ‘ptn3460_probe’:
    drivers/gpu/drm/bridge/ptn3460.c:333: error: implicit declaration of function ‘devm_gpiod_get’
    drivers/gpu/drm/bridge/ptn3460.c:333: warning: assignment makes pointer from integer without a cast
    drivers/gpu/drm/bridge/ptn3460.c:340: error: implicit declaration of function ‘gpiod_direction_output’
    drivers/gpu/drm/bridge/ptn3460.c:346: warning: assignment makes pointer from integer without a cast

Add the missing #include <linux/gpio/consumer.h> to fix this.

As the resulting driver won't work with GPIOLIB=n anyway, make
DRM_PTN3460 depend on GPIOLIB || COMPILE_TEST.
