[U-Boot] [PATCH v3 09/15] i.MX6UL: isiot: Switch the mmc env based on devno

[Jagan Teki]

From: Jagan Teki <jagan at amarulasolutions.com>

Add board_mmc_get_env_dev

Switch the mmc env based on the mmc devno, instead of separately
defining a config item in include/configs using board_mmc_get_env_dev
- devno 0: sd/esd
- devno 1: mmc/emmc
