[igt-dev] [PATCH i-g-t 3/5] tests: Use igt_display_require

[Daniel Vetter <daniel.vetter@ffwll.ch>]

Remaining tests that have been overlooked and don't need any
invasive changes to limit the skipping to only the relevant parts.

v2: read-all-entries was supposed to be the original non-KMS test.
Split them up for clarity.
