[U-Boot] [PATCH v4 13/15] i.MX6Q: icorem6_rqs: Add modeboot env via board_late_init

Jagan Teki

From: Jagan Teki <jagan@amarulasolutions.com>

Add runtime, modeboot env which is setting mmcboot based
on the bootdevice so-that conditional macros for MMC via
CONFIG_BOOTCOMMAND should be avoided in config files.
