arm64: dts: allwinner: h616: Split Orange Pi Zero 2 DT 



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.
