[PATCH] backlight: lms283gf05: use GPIOF_INIT flags when using devm_gpio_request_one()

[Jingoo Han]

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