If spread spectrum is enabled and in use for a given pll we should not turn it off as it will lead to turning off display for crtc that use the pll (this behavior was observed on chelsea edp).

Looks good. I think an alternative would be to just always enable SS for DP/eDP rather than checking the DPCD since all DP connections run on the same PLL.
On discrete cards anyway. APUs are a little different, but the same idea holds.
