[PATCH 2/2] arm64: dts: allwinner: Enforce consistent MMC numbering

[Samuel Holland]

Traditionally, the sunxi-mmc device numbers matched the register address
order. However, that was broken by asynchronous probe, and now the MMC
device numbers are not deterministic. Add aliases to keep the device
numbers consistent between boots. Use the traditional order, since there
is no need to change it.
