Reverting https://patchwork.freedesktop.org/patch/336850/

Hi Thierry

For DP drivers using MSM chipsets, we are using drm_dp_link_configure, 
drm_dp_link_power_up and drm_dp_link_power_down functions. Here is the 
patch for reference:

https://patchwork.freedesktop.org/patch/343346/

We will be posting a newer version of the driver soon.

For that, we plan to revert 
https://patchwork.freedesktop.org/patch/336850/ as now there are more 
users of the functions and not just tegra.

Let us know if this is the right approach or shall we make the required 
functions local to our drivers.

Thanks

Abhinav
