Subject: [v2] drm/amdgpu: skip vram operation for BAMACO runtime
From: Likun Gao <likun....@amd.com>
Skip vram related operation for bamaco rumtime suspend and resume as vram is
alive when BAMACO.
It can save about 32ms when suspend and about 15ms when resume.
v2: add local adev variable for maco enablement which checked by device MACO
support cap and runtime method parameter to have a mix of devices that support
different runtime pm modes.
