Subject: [RFC v2 2/2] ARM: omap3: Consolidate thermal references to common omap3

Because the omap34xx, omap36xx and am3517 SoC's have the same
thermal junction limits, there is no need to duplicate the entry
multiple times.

This patch removes the thermal references from omap36xx and
omap34xx and pushes it into the common omap3.dtsi file with
the added benefit of enabling the thermal info on the AM3517.
