Ville Syrjälä ef79fafe9d drm/i915: Eliminate intel_dp.regs.dp_tp_{ctl,status}
Now that we've plumbed the crtc state all the way down we can
eliminate the DP_TP_{CTL,STATUS} register offsets from intel_dp,
and instead we derive them directly from the crtc state.

And thus we can get rid of the nasty hack in intel_ddi_get_config()
which mutates intel_dp during the readout.
