Several SoMs and boards are available that feature the Bouffalolab
bl808 SoC. Document the compatible strings.

I know you're only propagating an existing pattern, but the "SoC-based"
looks rather odd!

BTW, do you know of any other m1s compatible docks?
I couldn't find any other ones via Google, so maybe it is just worth
swapping the enum here for another const.
Either is fine by me though.

FWICT, there's no other m1s compatible docks, but in theory the SoM
can be used to build different docks, I just keep it as is since you
are fine with it too ;)
