drm/amdgpu: add amdgpu_virt_get_vf_mode helper function
the swsmu or powerplay(hwmgr) need to handle task according to different VF mode,
this function to help query vf mode.
vf mode:
1. SRIOV_VF_MODE_BARE_METAL: the driver work on host OS (PF)
2. SRIOV_VF_MODE_ONE_VF : the driver work on guest OS with one VF
3. SRIOV_VF_MODE_MULTI_VF : the driver work on guest OS with multi VF
