[U-Boot] [PATCH 3/4] imx6: icorem6_rqs: 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.
