Sync the hifive-unleashed-a00 dts from Linux with below commit details: commit <2993c9b04e616df0848b655d7202a707a70fc876> ("riscv: dts: HiFive Unleashed: add default chosen/stdout-path") Idea is to periodically sync the dts from Linux instead of tweaking internal changes one after another, so better not add any intermediate changes in between. This would help to maintain the dts files easy and meaningful since we are reusing device tree files from Linux.
