The DP PHYs on X1E80100 need the ref clock which is provided by the TCSR CC.
The current X Elite devices supported upstream work fine without this clock, because the boot firmware leaves this clock enabled. But we should not rely on that. Also, even though this change breaks the ABI, it is needed in order to make the driver disables this clock along with the other ones, for a proper bring-down of the entire PHY.
So lets attach it to each of the DP PHYs in order to do that.
