Use the implicit kref infrastructure to free the container struct amdgpu_device, container of struct drm_device.
First, in drm_dev_register(), do not indiscriminately warn when a DRM driver hasn't opted for managed.final_kfree, but instead check if the driver has provided its own "release" function callback in the DRM driver structure. If that is the case, no warning.
Remove drmm_add_final_kfree(). We take care of that, in the kref "release" callback when all refs are down to 0, via drm_dev_put(), i.e. the free is implicit.
Remove superfluous NULL check, since the DRM device to be suspended always exists, so long as the underlying PCI and DRM devices exist.
