Testcase for 180 degree HW rotation

The test looks good to me (I haven't checked in details, the bar for igt
is quite a bit lower). It shows two gaps in the igt kms API:

   - Retrieving the primary plane (there's a series from Matt fixing this
     and exposing the primary plane through igt_output_get_plane())
True, thats why I am checking for type property in this test. Can be removed once Matt's patches are merged
   - Adding a set_property() convenience function
     (ala igt_plane_set_property("rotation", BIT(DRM_ROTATE_180)))
     (no-one is working on that just yet, can de done later)
Sure, will be good to have.

A small question before pushing this, have you checked that the test
correctly skips when running with a kernel without rotation support?
NO, I haven't tested that. Will try in sometime and let you know if I see any issue there.

Thanks,
