intel_extreme: remove unhandled generation defines

- 7xx (1st gen) has no driver in Haiku or is handled by the intel_810 driver
- PowerVR has no driver in Haiku

So there is no point in having those in the intel_extreme driver.

While I'm at it, fix the video timing/resolution constraints for
sanitize_video_mode.
