Rework internal bus handling and laptop bail-out

We used to bail out on any unknown laptop. However, modern systems with
SPI flashes don't suffer from the original problem. Even if a flash chip
is shared with the EC, the latter has to expect the host to send regular
JEDEC SPI commands any time.

So instead of bailing out, we limit the set of buses to probe. If we
suspect to be running on a laptop, we only allow probing of SPI and
opaque programmers. The user can still use the existing force options
to probe all buses.

This will obsolete some board-enables that could be moved to `print.c`
in follow-up commits.
