drm/i915: remove intel_crtc_cursor_set_obj() (v5)

Merge it into the plane update_plane() callback and make other
users use the update_plane() functions instead.

The fb != crtc->cursor->fb was already inside intel_crtc_cursor_set_obj()
so we fold intel_crtc_cursor_set_obj() inside intel_commit_cursor_plane()
and merge both paths into one.

v5 (by Matt):
 - Rebase onto latest di-nightly codebase
 - Drop extra unreference call when we fail to pin (Ville)
