In the macro for_each_oldnew_crtc_in_state() 'crtc_state' is provided
as a container for state->crtcs[i].new_state, but is not utilised in
some use-cases, so we fake-use it instead.
Fixes the following W=1 kernel build warning(s):
drivers/gpu/drm/imx/ipuv3-plane.c: In function ‘ipu_planes_assign_pre’:
drivers/gpu/drm/imx/ipuv3-plane.c:746:42: warning: variable ‘crtc_state’ set
but not used [-Wunused-but-set-variable]
