Use aliases to mmc nodes so the partition name for eMMC and SD card will
be consistent across boots.

To be honest I think this deserves a bit more pretext:
There used to be no way to specify the order of MMC controllers, and
the numbering was based on how the implementations added the devices.
For Linux, this changed when asynchronous probing was enabled for most
drivers, resulting in mmc device numbers jumping around.
With commit 1796164fac7e ("dt-bindings: mmc: document alias support"),
a way to specify fixed index numbers was provided.
Otherwise,

Same for the mt8183-kukui patch.
