I think it would make more sense to move the relevant not-shared part
out of the dtsi instead. Yes the duplication in orangepi-5 and orangepi-5b
should be fine.

Having a devicetree with so many /delete-node/ and /delete-property/
elements sprinkled throughout the file, will definitly cause readability
(and handling issues) in the future.

Additionally this makes all the comments in the file explaining individual
difference unnecessary.
