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.
