This reverts commit 4ba6b7a646321e740c7f2d80c90505019c4e8fce.
Altough 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.
