Vega20 stores a CUSTOM profile on the GPU, but it may not be valid. Add a bool to vega20_hwmgr to determine whether or not a valid CUSTOM profile has been set, and use that to check when a user requests switching to the CUSTOM profile without passing in any arguments. Then if the CUSTOM profile has been set already, we can switch to it without providing the parameters again
