[PATCH v2 1/3] arm64: dts: allwinner: h616: Split Orange Pi Zero 2 DT

From: Andre Przywara
Date: Fri Aug 04 2023 - 13:09:29 EST

The Orange Pi Zero 2 got a successor (Zero 3), which shares quite some
DT nodes with the Zero 2, but comes with a different PMIC.

Move the common parts (except the PMIC) into a new shared file, and
include that from the existing board .dts file.

No functional change, the generated DTB is the same, except for some
phandle numbering differences.
