PATCH 1/1 ARM: OMAP2+: AM43x: Add ID for ES1.2

ES1.2 is a minor variant of ES1.1. Major changes since ES1.1 are updating ROM for fixing the following boot modes:
- NAND boot
- UART boot
- Ethernet boot
- USB HOST/Client boot
This patch adds ID support for AM437x ES1.2 silicon. There are no additional kernel fixes required for ES1.2 silicon.
