ARM: OMAP: Add omap34xx revision detection for ES3.1.1
- Add omap34xx revision detection for ES3.1.1 silicon.
- Change default silicon to ES3.1.1
- Also minor bug-fix: ES2.0 rev field is 1, not 0.
- This means that ES2.0 silicon would have wrongly been
detected as unknown

Let me know if this should be split into a bug-fix patch,
and a separate patch for adding ES 3.1.1 revision info.
I felt the change was too minor to split out, since
ES2.0 silicon is rare.
This patch is against linus' tree - so the cpu.h
change will apply with an offset
