drm: Introduce pixel_source DRM plane property
Add support for pixel_source property to drm_plane and related
documentation. In addition, force pixel_source to
DRM_PLANE_PIXEL_SOURCE_FB in DRM_IOCTL_MODE_SETPLANE as to not break
legacy userspace.
This enum property will allow user to specify a pixel source for the
plane. Possible pixel sources will be defined in the
drm_plane_pixel_source enum.
Currently, the only pixel sources are DRM_PLANE_PIXEL_SOURCE_FB (the
default value) and DRM_PLANE_PIXEL_SOURCE_NONE.
