After testing this change, it breaks the driver during probing.

Why exactly does it break probing? Maybe the GPIO polarity defined in
the device tree is wrong?

I had a quick look into GPIOD_OUT_HIGH & LOW definitions, and they
seem to never be 0 or 1.

If you do a grep in all gpiod_set_value_cansleep() usages in the
kernel tree, there is not a single case where  GPIOD_OUT_HIGH or
GPIOD_OUT_LOW is passed as argument of gpiod_set_value_cansleep().
