[Intel-gfx] [PATCH i-g-t 04/12] lib/igt_kms: Allow setting any plane property through the universal path

[Maarten Lankhorst]

Blacklist some explicit atomic properties. We could theoretically set
them but that's not what the legacy path is for. :)

When adding new properties, this means we could test those through
the legacy commit.
