Nico Huber uploaded patch set #3 to this change.
gma bxt: Implement CDClk switching
Again, very similar procedure to the previous generations. The
CDClk is limited to 624MHz (no fuses). Dot clocks can run at the
full CDClk speed.
If all pipes are disabled, we set CDClk to its reference rate.
In this state, the display engine is not operational and neither
are the DP Aux ports. So we have to implement Enable_CDClk() to
allow display probing without any pipe enabled.
