  From sdm845 onwards we need to ensure the VFE is powered on prior to
switching on the CSID.

Alternatively we could model up the GDSCs and clocks the CSID needs
without the VFE but, there's a real question of the legitimacy of such a
use-case.

For now drawing a line at sdm845 and switching on the associated VFEs is
a perfectly valid thing to do.

Rather than continually extend out this clause for at least two new SoCs
with this same model - making the vfe_get/vfe_put path start to look
like spaghetti we can simply test for >= sdm845 here.
