[Intel-gfx] [PATCH 48/59] drm/arc: Drop fb/crtc check in arc_pgu_update

[Daniel Vetter]

First it's redundant, fb and crtc are only ever both set or not set.
2nd, the atomic_check code in simple display pipe helpers guarantees
that this never happens. So nice bugfix for arcpgu driver here, since
it was lacking a call to drm_atomic_helper_check_plane_state().
