e9685967bb i.MX6UL: isiot: Switch the mmc env based on devno
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

0dd259a1b1 i.MX6UL: isiot: Add mmc_late_init
Let the runtime code can set the mmcdev and mmcroot based
on the devno using mmc_get_env_dev instead of defining
separately in build-time configs using mmc_late_init func.

2e2a8dc635 i.MX6UL: isiot: Add modeboot env via board_late_init
Add runtime, modeboot env which is setting mmcboot, or
nandboot based on the bootdevice so-that conditional
macros b/w MMC and NAND for CONFIG_BOOTCOMMAND should
be avoided in config files.

cde5aa3761 imx6: isiotmx6ul: Update SPL board boot order for eMMC
SPL mmc device index is get based on the boot device, like
- BOOT_DEVICE_MMC1 for mmc device 0
- BOOT_DEVICE_MMC2 for mmc device 1

Currently BOOT_DEVICE_MMC1 is setting both SD/eSD and MMC/eMMC
boot devices in i.MX, So u-boot is loading from mmc device 0 even
"if the board booting from SD/eSD or MMC/eMMC"

So, this patch set BOOT_DEVICE_MMC2 for MMC/eMMC so for MMC/eMMC
the u-boot is loading from mmc device 1 and the board file need to
take care if the board have different mmc device order intialization.
