Igor Matheus Andrade Torrente bfcb1adc14 backend-drm: Drop support to non universal plane drivers
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.
