drm/amdgpu: Add amdgpu suspend-resume code path under SRIOV
commit 3b7329cf5a767c1be38352d43066012e220ad43c upstream.
- Under SRIOV, we need to send REQ_GPU_FINI to the hypervisor
during the suspend time. Furthermore, we cannot request a
mode 1 reset under SRIOV as VF. Therefore, we will skip it
as it is called in suspend_noirq() function.
- In the resume code path, we need to send REQ_GPU_INIT to the
hypervisor and also resume PSP IP block under SRIOV.
