drm/i915: Don't call intel_plane_restore() when the prop value didn't
change
No point in calling intel_plane_restore() in .set_property() if the
value didn't change.
More importantly this papers over a bug where the current primary plane
code forgets to update the user coordinates we store under intel_plane
unless the primary plane .update_plane() hook is actually called. This
means we have 0 in the coordinates straight after boot and any call
to intel_restore_plane() (such as from restore_fbdev_mode()) will
actually turn off the primary plane. This mess needs to be fixed properly
but that's a bigger task and the first step there is killing off
intel_pipe_set_base() and just calling the primary plane
.update_plane() hook. For the immediate problem of black screen after
boot this small patch is enough to hide it.
The problem originates from these two commits:
