Simple test case that reproduces the bug.
On BayTrail, page flipping to a bo that has a different tiling format than the
current front buffer does not work properly. The new buffer is scanned out
using the tiling format of the fb used in the drmModeSetCrtc() call.
The attached program reproduces the bug. It works properly on SandyBridge. The
expected behavior is for the even scanlines of the display to be colored, and
the odd ones black.</pre>
