Changing this driver to the gpiod API requires the use of the
new-style header, depending on the configuration:

drivers/video/fbdev/ssd1307fb.c: In function 'ssd1307fb_probe':
drivers/video/fbdev/ssd1307fb.c:569:15: error: implicit declaration of function 'devm_gpiod_get_optional';did you mean 'devm_regulator_get_optional'? [-Werror=implicit-function-declaration]
drivers/video/fbdev/ssd1307fb.c:570:11: error: 'GPIOD_OUT_LOW' undeclared (first use in this function)

Fixes: 72db3335 ("fbdev: ssd1307fb: Start to use gpiod API for reset gpio")
