Sure this works as intended, now the platform device id is off, and at
least for my 3.0 testing it is no longer able to open the console,
unless I explicit set the id field again.
Example on NGW100 mkII I use USART instance 1 as serial console, if not
setting the platform device id to 0 (re-mapping), then I get a warning
about unable to open console.
Is you clock optimization an additional patch?

AVR32 needs this to be present to work independent of which USART
peripheral the user chooses to use for console.
