ARM: DRA752: Add ID detect for ES2.0
ES2.0 is a minor variant of ES1.1. ES2.0 is an incremental revision
with various fixes including the following:
- reset logic fixes
- few assymetric aging logic fixes
- MMC clock rate fixes
- Ethernet speed fixes
- edma fixes for mcasp
NOTE: even though we use a compatible of dra742 and dra752, the usage in
the Linux kernel is more or less interchangable - we use dra752 more
often in the linux kernel compared to dra742 and 4.2-rc6
