[Intel-gfx] [PATCH i-g-t 08/12] lib/igt_kms: Add igt_$obj_has_prop functions

[Maarten Lankhorst]

This allows test to test whether a property is supported, in
a nice and clean way. It removes the need for special case
functions like igt_plane_supports_rotation.

Convert the users of igt_plane_supports_rotation and remove the
extra check in drm_plane_commit, this is already checked below
when setting plane properties.
