<title>drm/amd/powerplay: enable pp one vf mode for vega10</title>

<id>c9ffa427db34e6896523f0ef0c172a0bbb77c9ad</id>
<content type='text'>
Originally, due to the restriction from PSP and SMU, VF has
to send message to hypervisor driver to handle powerplay
change which is complicated and redundant. Currently, SMU
and PSP can support VF to directly handle powerplay
change by itself. Therefore, the old code about the handshake
between VF and PF to handle powerplay will be removed and VF
will use new the registers below to handshake with SMU.
mmMP1_SMN_C2PMSG_101: register to handle SMU message
mmMP1_SMN_C2PMSG_102: register to handle SMU parameter
mmMP1_SMN_C2PMSG_103: register to handle SMU response

v2: remove module parameter pp_one_vf
v3: fix the parens
v4: forbid vf to change smu feature
v5: use hwmon_attributes_visible to skip sepicified hwmon atrribute
v6: change skip condition at vega10_copy_table_to_smc

we can simplify all those unnecessary function under
SRIOV for vega10 since:
1) PSP L1 policy is by force enabled in SRIOV
2) original logic always set all flags which make itself
   a dummy step

besides,
1) the ih_doorbell_range set should also be skipped
for VEGA10 SRIOV.
2) the gfx_common registers should also be skipped
for VEGA10 SRIOV.

SR-IOV host side will send IDH_QUERY_ALIVE to guest VM to check
if this guest VM is still alive (not destroyed). The only thing
guest KMD need to do is to send ACK back to host.

Under vega10 virtualuzation, smu ip block will not be added.
Therefore, we need add pp clk query and force dpm level function

v2: add get_pp_clk existence check and use kzalloc to allocate buf

v3: return -ENOMEM for allocation failure and correct the coding style

sriov's gpu_recover inside xgpu_ai_mailbox_flr_work would cause duplicate recover in TDR.
TDR's gpu_recover would be triggered by amdgpu_job_timedout,
