davinci: da8xx: Add support for DA830/OMAP-L137 EVM board 



Add support for the DA830/OMAP-L137 Evaluation Module (EVM)
from TI.  The EVM has User Interface (UI) and Audio cards
that can be connected which contain various devices.
Support for those devices and ones on the EVM will be
added in subsequent patches.

Additional generalizations for future SoCs in da8xx family done by
Sudhakar Rajashekhara and Sekhar Nori.
