Functions armada_drm_crtc_atomic_flush &
armada_drm_crtc_atomic_enable don`t use the second parameter.
So we may get warning like :
warning: unused parameter ‘***’ [-Wunused-parameter].
This change is to fix the compile warning with -Wunused-parameter.

Under what circumstances do we build the kernel with that warning
enabled?
