Subject: amdgpu/pm: Disallow managing power profiles on SRIOV for Sienna
 Cichlid
Git-commit: 1b85257290f382a78adba1b0a5b59a95cebdfa2f
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Managing power profiles mode is not allowed in SRIOV mode for Sienna
Cichlid. This patch is adjusting the "pp_power_profile_mode" and
"power_dpm_force_performance_level" accordingly.
