Revert "drm/atomic: Loosen FB atomic checks"
This reverts commit f1e75da5364e780905d9cd6043f9c74cdcf84073.
Although the Solid Fill planes patchset got all reviews and
acknowledgements, it doesn't fulfill requirements for the new uABI. It
has neither corresponding open-source userspace implementation nor the
IGT tests coverage. Reverting this patchset until userspace obligations
are fulfilled.
