Revert "drm: Introduce pixel_source DRM plane property"

Browse Source 
This reverts commit e50e5fed41.

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.

* pixel_source:
* pixel_source is set up with drm_plane_create_pixel_source_property().
* It is used to toggle the active source of pixel data for the plane.
* The plane will only display data from the set pixel_source -- any
* data from other sources will be ignored.
*
* For non-framebuffer sources, if pixel_source is set to a non-framebuffer
* and non-NONE source, and the corresponding source property is NULL, then
* the atomic commit should return an error.
*
* Possible values:
*
* "NONE":
* No active pixel source.
* Committing with a NONE pixel source will disable the plane.
*
* "FB":
* Framebuffer source set by the "FB_ID" property.
*
* Note that all the property extensions described here apply either to the
* plane or the CRTC (e.g. for the background color, which currently is not
* exposed and assumed to be black).

* Returns:
