This patch fixes a regression introduced by commit 31c3dc7488
("leds: leds-ns2: use gpio_request_one").
gpio_request_one is called with a wrong flag value: The initial GPIO
state is used to configure the direction (bit 0) instead of the value
(bit 1). As a result, if the initial GPIO state is non null then the
GPIO will be configured as input.
This patch fixes the issue by using the dedicated macros
GPIOF_OUT_INIT_{LOW,HIGH} to configure the initial GPIO value.
