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 Signed-off-by: Vishal Mahaveer <vishalm@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
