[igt-dev] [PATCH i-g-t] tests/kms_flip_tiling: Check for mode when performing flip with Y/Yf tiling

[Mika Kahola]

Kernel doesn't support Y or Yf tiling for interlaced modes. In kms_flip_tiling test case
we are missing such a check. Let's add a requirement that whenever we try to do flip with Y/Yf
tiling, we ensure that we have non-interlaced mode selected.
