[Intel-gfx] [PATCH i-g-t] kms_universal_plane.c: Update sanity checks for gen9

[Matt Roper]

SKL and BXT have some new plane capabilities that previous generations
didn't have; we need to update some of our universal plane tests to
expect success rather than failure when running on these platforms.
