This patch fixes a regression introduced by commit b0053aaa23
("leds: renesas: use gpio_request_one").

gpio_request_one is called with a wrong flag value: The brightness is
used to configure the direction (bit 0) instead of the value (bit 1).

This patch fixes the issue by using the dedicated macros
GPIOF_OUT_INIT_{LOW,HIGH} to configure the initial GPIO value.

Hi Simon Guinot,

The same patch was already merged to Bryan's git.
Thus, this patch is not necessary.

Best regards,
