[coreboot] autoport

[Martin Roth]

Hi phcoder,
  I'm trying to resolve a question that came up with inteltool &
autoport regarding how the probing of graphics should behave.

Stefanct kept having his board reboot when he was running autoport, so
he added this change to separate out the graphics call as "unsafe"
when probing all.

Because this changes the behavior of autoport, I suggested we ask the
user what they want to do when running autoport.

What's your opinion?
