Does this mean OpenSBI uses a different uart from uart1?

If not that means both Linux in S-mode and OpenSBI in M-mode will
both try to use uart1 at the same time. It might work by chance,
but a much better solution would be to just use "earlycon".
You already define chosen/stdout-path to point at uart1 and the
driver for 'snps,dw-apb-uart' implements earlycon so it should
work much the same.
