Add the missing vio-supply to all usages of the AW2013 LED controller
to ensure that the regulator needed for pull-up of the interrupt and
I2C lines is really turned on. While this seems to have worked fine so
far some of these regulators are not guaranteed to be always-on. For
example, pm8916_l6 is typically turned off together with the display
if there aren't any other devices (e.g. sensors) keeping it always-on.

I omitted the Fixes: tag here as it would be 5 separate commits, and
it's really only useful to backport this to v6.6+ since this is where
the necessary driver addition landed (see commit baca986e1f2c3 ("leds:
aw2013: Enable pull-up supply for interrupt and I2C"). I'm not aware
that anyone actually ran into trouble with this missing regulator yet.
