We can leave the MACHINE_FEATURES as is, that way we still build the GUI bits,
only the below line is needed to switch to software rendering.

Otherwise, I would have preferred this patch the other way, have a new branding
to use the old unsupported kernel. Either way this seems reasonable for now.

There's at least one demo in Arago that requires HW accelerated graphics and 
doesn't make sense with software rendering, hence it still checks for "gpu" 
machine feature.

I guess we could switch Arago to default to 6.1, as long as we keep meta-ti on 
5.10 for the migration phase.
