davinci: Add base DA850/OMAP-L138 SoC support
The DA850/OMAP-L138 is a new SoC from TI in the same family as DA830/OMAP-L137. Major changes include better support for power management, support for SATA devices and McBSP (same IP as DM644x). DA850/OMAP-L138 documents are available at http://focus.ti.com/docs/prod/folders/print/omap-l138.html.
