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.
