Well at least move them. And if there are clear dedicated
register ranges there claimed only by a single device driver,
then those drivers should be just regular loadable driver
modules doing of_ioremap on the range. And in that case they
can be removed.

We have examples of both in dra7.dtsi, pbias_regulator using
the scm_conf via syscon, and then dra7_pmx_core ioremapping
a dedicated register range. So unless there are other messy
register ranges like the scm_conf area then there should not
be need for other syscon areas.
