The PCH can drive several reference clocks simultaneously, and needs to with multiple display configurations. So we can't just clobber the existing state everytime we set a mode, we need to take into account what the other CRTCs are doing at the time. Doing so fixes an issue where you'd lose the LVDS display at boot if you had an LVDS+DP config.
