Subject: [PATCH] arm64: dts: freescale: fsl-ls1028a-tqmls1028a-mbls1028a: switch mmc aliases

All modern TQ-Systems boards follow the convention that mmc0 is the eMMC
and mmc1 is the SD-card when both interfaces exist, reducing differences
between boards for both documentation and U-Boot code (which uses the
same Device Trees). Adjust the recently added MBLS1028A Device Tree
accordingly.

Fixes: 0538ca1f102d ("arm64: dts: ls1028a: Add mbls1028a and mbls1028a-ind devicetrees")
Signed-off-by: Matthias Schiffer <matthias.schiffer@...tq-group.com>

Notes:

- Gregor (author of the fixed commit) is not working for TQ anymore, so
  his mail address does not exist anymore and he is omitted from cc
- Normally we would consider modifying the aliases a breaking change;
  fortunately, these Device Trees are only in linux-next for now
