drm/amd: Evict resources during PM ops prepare() callback
Linux PM core has a prepare() callback run before suspend.
If the system is under high memory pressure, the resources may need
to be evicted into swap instead. If the storage backing for swap
is offlined during the suspend() step then such a call may fail.
So move this step into prepare() to move evict majority of
resources and update all non-pmops callers to call the same callback.
