All this would only execute on #ifdef VT_CONSOLE right now and I think
they can be gated further by a new Kconfig like VT_CONSOLE_PREFERRED, if
that'd make it better.

I was working on next-20200430 where that patchset is already included,
can confirm it doesn't solve this problem. I hope I've correctly avoided
breaking it by setting its "has_preferred_console" variable (thus this
patchset somewhat depends on that).
