[ARM] OMAP3: update ES level flags to discriminate between post-ES2 revisions
Some OMAP3 chip behaviors change in ES levels after ES2. Modify the
existing omap_chip flags to add options for ES3.0 and ES3.1.
Add a new macro, CHIP_GE_OMAP3430ES2, to cover ES levels from ES2
onwards - a common pattern for OMAP3 features. Update all current
users of the omap_chip macros to use this new macro.
Also add CHIP_GE_OMAP3430ES3_1 to cover the USBTLL SAR errata case
(described and fixed in the following patch)
