Added Petri Latvala

The best way to handle i915 loading in BAT would be to blacklist
i915 in boot and have igt@i915_module_load@load as the first
thing in fast-feedback.testlist. This would catch any i915 issue
to a test and we wouldn't need to do tricks with ci@boot
pseudotest.

Most of the CI parts are already in place. The IGT commit to
change fast-feedback needs to be coordinated.
