leds: leds-lt3593: set devm_gpio_request_one() flags param correctly
The devm_gpio_request_one() flags parameter was set to:
GPIOF_DIR_OUT | state
GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below:
GPIOF_DIR_OUT (0 << 0)
GPIOF_DIR_IN (1 << 0)
So, when 'state' 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 devm_gpio_request_one().
