Subject: [PATCH V4 3/6] ARM: dts: OMAP4: add clock nodes for CPU

OMAP443x, OMAP446x and OMAP447x platforms use dpll_mpu clock.
Add same to common definition.

RFC of this patch approach for OMAP3 was discussed in http://marc.info/?t=136370325600009&r=1&w=2
along with the detailed context as to why this is an intermediate step.

previous revisions of cpufreq-cpu0 support do not use this approach.
[Probably belongs to Benoit's tree]
