Subject: [PATCH] arm64: dts: freescale: sl28: correct MMC order

Commit 342ab37ecaf8 ("arm64: dts: freescale: use fixed index mmcN for
layerscape") hardcoded the order of the MMC devices. This doesn't fit
the sl28 boards, which come with an onboard eMMC. Thus use the more
natural order for the eMMC and SD card. Use /dev/mmcblk0 for the eMMC
and /dev/mmcblk1 for the SD card which is removable by the user.

Please note, that the images for this board already use root=UUID=,
therefore the actual device number doesn't matter for booting.
