Replacing bootargs with stdout-path property in chosen node allows using
early console by adding just 'earlycon' parameter to the kernel command
line.

Remove the "console=ttySAC..." argument from DTSes having a proper
stdout-path property. To make the code functionally equivalent, add the
serial port baud rate and parity.
