[igt-dev] [PATCH i-g-t v3 3/4] tests/kms_plane_lowres: Don't fail tests when missing format/mod support

[Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>]

The kms_plane_lowres subtests will fail on non-i915 hardware because
of the devid lookups and tiling format requirements.

This patch makes use of the igt_display_has_format_mod() helper to
check for support before failing fb creation.

The tests still won't fully run yet on i915 hardware because they'll
skip during calls to igt_assert_plane_visible - those require an i915
extension to get the CRTC/plane set for a given pipe.

v2: Use igt_display_has_format_mod helper (Ville)
v3: Move variable declarations to loop scope (Ville)
