drm/msm/mdp4: Fix modifier support enabling

Browse source

commit 35cbb8c91e upstream.

Setting the cap without the modifier list is very confusing to
userspace. Fix that by listing the ones we support explicitly.

Stable backport so that userspace can rely on this working in a
reasonable way, i.e. that the cap set implies IN_FORMATS is available.
