omap3: Update method to detect si revision
This patch ensures that all silicon revisions
are detected. (Current implementation cannot
detect ES1.0).
In the process, the 'seemingly' hardcoded macros
identifying cpu revision (e.g. CPU_ES1P1) have
been updated to include the CPU name as well.
(The mapping of IDCODE value to silicon revision
may not be same across different OMAP families).
