Subject: [PATCH 1/1] ARM: dts: orange-pi-zero-plus2: use fixed mmc indexes

Driver sunxi-mmc has recently been switched to asynchronous probe.
As a result, mmc indexes can be shuffled breaking existing setups
where UUIDs are not used for boot devices. Pin mmc indexes to keep
running the systems where fixed MMC or eMMC are specified,
e.g. root=/dev/mmcblk0p2.
