Subject: [PATCH] drm: Remove drm_fbdev_cma_set_suspend()

drm_fbdev_cma_set_suspend() is not getting called from
any other places. If there is no plan to use it in future
we can remove this API.

cma version of fbdev helpers are indeed getting subsumed by fbdev helpers
at large, so this makes sense I think.

Applied for 4.20, thanks for your patch.
