[RFC 6/9] ARM: dts: omap443x: Add opp-modifier entry and add higher OPPs

[Dave Gerlach]

Add an entry for opp_modifier which configures OPPs on omap443x. 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 omap443x.
