backports: disable some regulator drivers on 3.4 and 3.5

We enabled regulator subsystem support as of 3.4 but given that
the regulator subsystem has advanced quite a bit on 3.5 and 3.6
and that we cannot backport the regulator as its part of the
core kernel we have no option but to only enable drivers on their
kernels if they don't depend on the new regulator features.
