[PATCH RFC 0/3] first pass converting omap4 clock data to DT

This is a very incomplete conversion of a handful of OMAP4 PRCM clocks
from the statically defined clock data in
arch/arm/mach-omap2/cclock44xx_data.c to a new dts file in
arch/arm/boot/dts/omap4-clocks.dtsi.

I am not a DT expert so many of the choices here may be quite disgusting
to look at, or may be on the right path. In particular I simply include
the new omap4-clocks.dtsi from omap4.dtsi, which feels a bit kludgey.
Also this series depends on the basic clock bindings RFC I posted
earlier today[1].

I actually have an omap4-clock.dtsi file with many more clocks converted
to the mux-clock, divider-clock, fixed-clock, fixed-factor and
(unpublished) gate-clock bindings in my local repo, but it is not
currently booting. I wanted to get this early preview out regardless.
