drm/amdgpu: add a dev_pm_ops prepare callback (v2)
as per:
https://www.kernel.org/doc/html/latest/driver-api/pm/devices.html
The prepare callback is required to support the DPM_FLAG_SMART_SUSPEND
driver flag. This allows runtime pm to auto complete when the
system goes into suspend avoiding a wake up on suspend and on resume.
Apply this for hybrid gfx and BOCO systems where d3cold is
provided by the ACPI platform.
v2: check if device is runtime suspended in prepare.
