commit b835d6953009dc350d61402a854b5a7178d8c615 upstream.
The configuration registers for the LED group have inverted
polarity, which puts the GPIO into open-drain state when used in
GPIO mode. Switch to '0' for GPIO and '1' for LED modes.
Fixes: 87466ccd9401 ("pinctrl: armada-37xx: Add pin controller support for Armada 37xx")
