From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
When the sprite is covering the entire pipe (and color keying is not
enabled) we currently try to automagically disable the primary plane
which is fully covered by the sprite.
Now that .crtc_disable() will simply disable planes by setting the
state->visible to false, the sprite code will actually end up
re-enabling the primary after it got disabled, and then we proceed to
turn off the pipe and are greeted with some warnings from
assert_plane_disabled().
The code doing the automagic disable of covered planes needs to
rewritten to do things correctly as part of the atomic update (or simply
removed), but in the meantime add a a bit of duct tape and simply have
the sprite code check the primary plane's state->visible before
re-enabling it.
