The reason we don't support descriptors is that the GPIO API currently
doesn't support having more than one user of a descriptor but GPIO
enables for regulators get shared often enough to be interesting. If
drivers start using this then that'd mean that the shared enable support
would become erratic depending on which driver was in use.
