sna: Haswell reintroduces MI_LOAD_SCAN_LINES
Better late than never? Interestingly only available from the BLT ring,
which makes accurate waiting for XVideo (which must use the render ring)
impossible in the current form - we need to render to a temporary then
do a vsynced blit in this case.

Chipset :Lynx Point-LP A0(QDBY)
Baseboard: Intel ULT board code named Whitetip Mountain Fab 3.
Kernel: 3.8.0-12-generic
OS: Ubuntu Raring Ringtail (development branch)
Details:
whatever set the resolution by "xrandr -s [0..3]" or by the GUI to set the
resolution, the screen will become garbage screen. And the demsg will appear
"[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung"
Reproducible: always
Steps to Reproduce:
1.login the system
2.set the resolution
Actual Results:
Garbage screen became.
Reason: It is the issue of xf86-video-intel package, upstream xf86
-video-intel hasn't this issue. Both of them have a version of 2.21.4,
I compared the source code of ubuntu 13.04 and upstream xf86-video-
intel, they are the same. But the configure.ac files are different.
