Add support for OMAP4460 revision detection.

  Without yet adding in the underlying code, extend the revision
checking code to return additional values for PandaBoard ES boards.
Much of the code was taken close to verbatim from U-Boot.
compile tested, and confirmed that this code behaves identically to
the original panda configure and build for the three pandas i have:

  * Rev A2 (boots)
  * Rev EA3 (boots)
  * Rev B1 ES (no output)

so while there's still work to be done, this at least represents the
necessary infrastructure to start *recognizing* panda ES boards.
