ARM: sun8i: a23/a33: drop bl_en_pin GPIO pinmux in reference design DTSI
The bl_en_pin GPIO pinmux is configured as "gpio_in", which makes it conflicts with the real GPIO usage (out), and makes the backlight not usable. Drop the GPIO pinmux for it, thus this GPIO can be correctly used. Signed-off-by: Icenowy Zheng <icenowy@aosc.xyz> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
