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