[igt-dev] [PATCH] tests/kms_plane_alpha_blend: skip coverage tests on missing enum

[Simon Ser]

Some KMS drivers support the KMS "pixel blend mode" plane property,
but don't support the "Coverage" mode. This enum entry is missing
to indicate lack of support as seen in this drm_info exerpt:

    "pixel blend mode": enum {None, Pre-multiplied} = Pre-multiplied

Skip the coverage tests in this case.
