Now that we have hooks to enable the atomic plane helpers, we can use
the plane helpers for our .update_plane() and .disable_plane()
entrypoints.
v2: Fix commit message typo (Bob)
v3: Rebased on top of Gustavo Padovan's patches to kill off
intel_crtc_cursor_set_obj() and intel_pipe_set_base().
v4: Rebase again on latest display refactor series. Now that previous
patches have smoothed the rough edges of the existing display code,
the transition here is much less painful.
Testcase: igt/kms_plane
Testcase: igt/kms_universal_plane
Testcase: igt/kms_cursor_crc
