ARM: ti: consolidate mmc environment variables
Introduce include/environment/ti/mmc.h that consolidates environment variable definitions for various TI boards that support MMC/SD. This allows reuse of same environment variables on non-ARMv7 TI platforms like OMAP-L138 for example. While at it, move DFU-related environment variable includes to only non-SPL builds for AM335x and AM437x since they are not really used for SPL today.
