[PATCH 1/2] arm64: dts: mt7622: fix console output issue on rfb1

[Ryder Lee]

The issue was introduced by Kernel CI:
https://kernelci.org/boot/id/5bbdcbad59b5146fc5b43592/

Fix this by using a 'stdout-path' property that points to the device.

The issue was *found* by kernelCI, not introduced by kernelCI. ;)

Note that this patch fixes the problem where there is no more console
output, but current mainline still doesn't boot as there's another
crash: http://termbin.com/zitb
