Add an entry for opp_modifier which configures OPPs on omap4460. Within
this, nodes are defined with the opp-modifier propety that are defined
as a list of frequency, offset from base register, and register value.
The CPU node passes a phandle to the appropriate child node to get the
correct table.
This patch also adds higher eFused OPPs for omap4460.
