florian 1b6d4fd149 [package] flashrom: use msr path compatible w/ hotplug2
The issue wasn't that flashrom-0.9.3 was broken, but that the incompatible device path put the box into a funky state that couldn't be reverted.

This fix causes it to use the hotplug2 path.

With this, we don't need to revert to 0.9.1, superseding my early patch to revert...
