Previous implementation uses a hard-coded register value to check if
the current serial entity is the console entity.
Now the lantiq serial driver uses the aliases for the index of the
serial port.
The lantiq danube serial dts are updated with aliases to support this.

You generally want the aliases to be part of the board specific file,
not every board numbers their serial ports in the same way.

In this chip only asc1 can be used as console, so serial0 is defined in
chip specific file.
