arm64: dts: mediatek: mt7986a: bpi-r3: Convert to sugar syntax

Overlay syntactic sugar for generating target-path fragments is
supported by the version of dtc supplied with the kernel since commit
50aafd60 ("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.
