This is clearly not something that should be open coded in individual
drivers, aside from the code duplication it is obviously possible to
have two different chips supplying each other which this wouldn't help
at all.  Is this happening for you with current kernels, we have a few
mechanisms for deferring bindings of supplies which should help here.
