gemini: Stop enforcing command line

The command line enforced by the kernel is harmful, we want to
use the command line passed from the device tree. This is
especially important for the SQ201, Teltonika RUT and WBD111
which has a console set to 115200n8 and not 19200n8 like all
the others, so their consoles will be confusingly changing
baudrate between boot loader and kernel. The setting in the
device tree corresponds to what the boot loader is using.
