python: remove "earlycon" linux option from LupV board
This option doesn't work and triggers a warning by Linux when booting.
To make it work, we need a chosen node containing an `stdout-path`
property in the FDT which currently doesn't exist.
I tried to create via a couple of approaches it but encountered multiple
issues:
1. One can set `stdout-path` to the complete path of the tty device, but
such path is impossible to get programmatically (unless it's
hardcoded).
2. One can set `stdout-path` as a reference to a label. While labels are
possible to generate easily, reference to labels cannot be generated
with the current FDT library.
So just remove this option for the time being.
