If CONFIG_DRM_LONTIUM_LT8912B=m, the following errors will be seen while
compiling lontium-lt8912b.c
drivers/gpu/drm/bridge/lontium-lt8912b.c: In function
‘lt8912_hard_power_on’:
drivers/gpu/drm/bridge/lontium-lt8912b.c:252:2: error: implicit
declaration of function ‘gpiod_set_value_cansleep’; did you mean
‘gpio_set_value_cansleep’? [-Werror=implicit-function-declaration]
gpiod_set_value_cansleep(lt->gp_reset, 0);
^~~~~~~~~~~~~~~~~~~~~~~~

^~~~~~~~~~~~~~~~~~~~~~~

GPIOF_INIT_HIGH

v2:
- add header file <linux/gpio/consumer.h> for lontium-lt8912b.c instead
of add config dependence for CONFIG_DRM_LONTIUM_LT8912B
