SKL specs

igt at kms_chv_cursor_fail subtests start to fail on SKL due to
Bad commit: a5509abda48ecfc133fac6268e83fc1a93dba039 drm/i915: Fix legacy
cursor vs. watermarks for ILK-BDW
Good commit: commit 9ce53745

Bisecting was done on my dev-SKL, but below failure data is taken from
SKL_NUC6i5SYB (see attachments) for 
commit 7f38bb9ea553c613223b705326c1b8d1a8fc4a90
