d27252b570 amdgpu/pm: prevent array underflow in vega20_odn_edit_dpm_table() 
In the PP_OD_EDIT_VDDC_CURVE case the "input_index" variable is capped at
2 but not checked for negative values so it results in an out of bounds
read.  This value comes from the user via sysfs.

The workaround designed for some specific ASICs is wrongly applied
to SMU13 ASICs. That leads to some runpm hang.

d09ef24303 drm/amdgpu: clarify DC checks 
There are several places where we don't want to check
if a particular asic could support DC, but rather, if
DC is enabled.  Set a flag if DC is enabled and check
for that rather than if a device supports DC or not.

ecc9b6e15a drm/amdgpu: Ignore stop rlc on SRIOV environment. 
For SRIOV, the guest driver should not do stop rlc. The host
handles programing RLC.

On SRIOV, the stop rlc will be hang (RLC related registers are
blocked by policy) when the RLCG interface is not enabled.
