It seems we are trying to approach a generic binding for DVFS operating
points.  In that case, we will need a generic library helper function
to parse it.  But since we already have such a library - OPP
(drivers/base/power/opp.c) in place, I would approach the same goal
in other way around, adding device tree binding for OPP.  Please see
the patch I just sent out below and comment.
