[boot-wrapper PATCH v2 6/9] configure: Use earlycon instead of earlyprintk

[Andre Przywara]

The arm64 Linux kernel dropped support for the "earlyprintk" command line
parameter a long time ago[1], instead it uses the earlycon parameter
now.

Replace earlyprintk with earlycon on the default command line, to see
early kernel output.

Ideally we would just say "earlycon" (without specifying an MMIO
address), but this relies on the stdout-path property in the /chosen
node, which the model DTs do not carry.
