On gmch platforms the normal pipe source CRC registers don't work for DP and TV encoders. And on newer platforms the single pipe CRC has been replaced by a set of CRC at different stages in the platform. Now most of our userspace tests don't care one bit about the exact CRC, they simply want something that reflects any changes on the screen. Hence add a new auto target for platform agnostic tests to use. v2: Pass back the adjusted source so that it can be shown in debugfs. v3: I seem to be unable to get a stable CRC for DP ports. So let's just disable them for now when using the auto mode. Note that testcases need to be restructured so that they can dynamically skip connectors. They also first need to set up the desired mode configuration, since otherwise the auto mode won't do the right thing. v4: Don't leak the modeset mutex on error paths. v5: Spelling fix for the i9xx auto_source function.
