This #include will cause an unnessary dependency from the amlogic tree
to the clock tree even though this patch is not currently using any of
the #defines from that header.  It will simplify the dependencies if you
drop this #include from this patch.

In my comment on the cover letter, I suggested adding a patch that also
switches the UART over to the new clock provider.  That is the patch
that should add this #include, since it will actually need #defines from
the header.

Doing it in that order means that we could merge this patch
independently of the clock driver, and then merge the UART switch-over
patch only after the driver (and headers) are merged.
