drm/amdgpu: use doorbell mgr for MES kernel doorbells
This patch: - Removes the existing doorbell management code, and its variables from the doorbell_init function, it will be done in doorbell manager now. - uses the doorbell page created for MES kernel level needs (doorbells for MES self tests) - current MES code was allocating MES doorbells in MES process context, but those were getting written using kernel doorbell calls. This patch instead allocates a MES kernel doorbell for this (in add_hw_queue). V2: Create an extra page of doorbells for MES during kernel doorbell creation (Alex) V4: Move MES doorbell size and page offset objects in this patch from patch 6.
