Remove all the backend code to support drivers without universal planes. From[1]: "The code needed to support kernels where DRM does not support uiniversal planes makes the DRM-backend a little more complicated, because it needs to create fake planes for primary and cursor. The lifetimes of the fake planes does not match the lifetime of "proper" planes, which is surprising." And since the universal planes left the experimetal flag in 2014[2] it is safe to remove the support now.
