ARM: sun8i: a23/a33: drop bl_en_pin GPIO pinmux in reference design DTSI

Browse Source 
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.
