[PATCH 2/7] drm/amdgpu: introduce grph object id from DAL.

Thu Apr 14 02:56:05 UTC 2016
From: Dave Airlie <airlied at redhat.com>
DAL has a graphics object id we should re-use this in the mainline
driver, and wrap around it for now.
This patch introduces the core of the grph functionality ported
from DAL.
