Up to now we've used the plane's modifier list as the primary
source of information for which modifiers are supported by a
given plane. In order to allow auxiliary metadata to be embedded
within the bits of the modifier we need to stop doing that.

Thus we have to make .format_mod_supported() aware of the plane's
capabilities and gracefully deal with any modifier being passed
in directly from userspace.

v2: Rebase after NV12
    Simplify

This seems like it would be a lot shorter if you just had a helper to
check if your format and modifier was in drm_plane->format_types and
drm_plane->modifiers, since then you wouldn't be duplicating your tables
and you wouldn't need has_ccs either.

However, it's not my driver and it unblocks vc4's patch, so:

I suppose. And I guess that's where I started originally :/

But I'm not sure if it's better go that route or the other route of
reducing the arrays to some simple supersets and also utilize
.format_mod_supported() in plane init to filter out the unsupported
formats when populating the plane's format list. Probably best not
dwell on this too much for now so that we can at least make some
progress :)

Thanks. I'm guessing we should push this into drm-misc-next so
that you can pile your core/sand bits on top?

That would be wonderful.

Now pushed. Had to resolve a few nv12 conflicts each way. I guess
someone else will get to deal with that same fun at some point
