leds: renesas: set gpio_request_one() flags param correctly
The gpio_request_one() flags parameter was set to:
GPIOF_DIR_OUT | !!brightness
GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below:
GPIOF_DIR_OUT (0 << 0)
GPIOF_DIR_IN (1 << 0)
So, when '!!brightness' is 1, the gpio pin can be set as input,
instead of output.
To prevent this problem, GPIOF_OUT_INIT flags should be used when
using gpio_request_one().
