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.
