[igt-dev] [PATCH i-g-t] tests/kms_plane_scaling: Check supported format for rotation

[Mika Kahola]

Let's align with kernel and add checks for formats that are
not allowed to do 90/270 rotation.

In dmesg we see for example, the following

"[drm:skl_plane_check [i915]] Unsupported pixel format Y210
little-endian (0x30313259) for 90/270!"
