Same comment as last time - why is this something which can be selected
in the binding?

The numbers still need to be defined in the binding, the point with the
defines is to make both code and DTs more readable but we need to know
what is actually going to go into the binary.

The idiomatic thing would be to use the pin name.

Don't do this (or the equivalent from the DACs) - we don't do this for
any other drivers, we shouldn't do it for this one. If we're going to
do something like this it should be generic not per driver hacks.

Just inline the set power function, or at the very least split it into
separate on and off functions - there is zero shared code between the
power on and off paths.
