[Intel-gfx] [PATCH i-g-t 2/2] igt/kms_rotation_crc: Add RGB565 90 degree test for gen>9

[Juha-Pekka Heikkila]

Gen10 onwards 90 and 270 degree rotations are supported for RGB565 format.

v2 (Ville Syrjälä):
As a side effect to keep bad-pixel-format test valid on all supported
platforms it need to use DRM_FORMAT_C8 now.

While at it clean up kms_rotation_crc test a bit, take out
test_plane_rotation_ytiled_obj() function as
test_plane_rotation() can basically do the same.
