drivers/video/backlight/lms283gf05.c: use GPIOF_INIT flags when using devm_gpio_request_one()

GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below:

   GPIOF_DIR_OUT   (0 << 0)
   GPIOF_DIR_IN    (1 << 0)

So, when !pdata->reset_inverted is 1, the gpio pin can be set as
input, instead of output.

To prevent this problem, GPIOF_INIT flag should be used when using
devm_gpio_request_one().
