Overlay syntactic sugar for generating target-path fragments is
supported by the version of dtc supplied with the kernel since commit
50aafd60898a8b3e ("scripts/dtc: Update to upstream version
v1.4.6-21-g84e414b0b5bc"). Hence convert the Bananapi R3 overlay
devicetree source files to sugar syntax, improving readability.

No changes in generated dtbo.
v3:
- Fix SoC part number,
v2:
- Rebase on top of commit e630c7b0b6a69f66 ("arm64: dts: mediatek:
replace underscores in node names") in next-20240215 and later.
