    drm/amd/display: Set minimum requirement for using PSR-SU on Phoenix
    
    [ Upstream commit cd2e31a9ab93d13c412a36c6e26811e0f830985b ]
    
    The same parade TCON issue can potentially happen on Phoenix, and the same
    PSR resilience changes have been ported into the DMUB firmware.
    
    Don't allow running PSR-SU unless on the newer firmware.
