Change in ...flashrom[master]: Rework internal bus handling and laptop bail-out

Hello Angel Pons, Arthur Heymans, Matt DeVillier, Thomas Heijligen, David Hendricks, Paul Menzel, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/28716 to look at the new patch set (#7). Change subject: Rework internal bus handling and laptop bail-out ...................................................................... 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.
