Revert "drm: Introduce solid fill DRM plane property"

Browse Source 
This reverts commit 85863a4e16.

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.
