[mlankhorst: Fix extra whitespace between functions.]
This is mostly code churn, with exception of a few places:
- intel_display.c has changes in intel_sanitize_encoder
- intel_ddi.c has intel_ddi_fdi_disable calling intel_ddi_post_disable,
and required a function change. Also affects intel_display.c
- intel_dp_mst.c passes a NULL crtc_state and conn_state to
intel_ddi_post_disable for shutting down the real encoder.
If we would pass conn_state, then conn_state->connector !=
intel_dig_port->connector and conn_state->best_encoder !=
to_intel_encoder(intel_dig_port).
We also shouldn't pass crtc_state, because in that case the
disabling sequence may potentially be different depending on
which crtc is disabled last. Nice way to introduce bugs.
No other functional changes are done, diff stat is already huge.
Each encoder type will need to be fixed to use the atomic states
separately.

The MST vs. SST selection should depend purely on the choice of the

based on the intel_dp->is_mst, which simply tells us whether the sink
is in MST mode or not. Instead derive the information from the encoder
type. Since the link training code deals in non-fake encoders, we'll
also need to keep a second copy of that information around, which we'll
now designate as 'link_mst'.

It's not clear when this lane configuration takes effect. The

enabling the PLL. To be safe preserve the current order and set things

manual powering toggling. So make the PHY enabling/disabling to happen
on-demand whenever we need either the corresponding AUX or port

corresponding PHY common lane power wells there, do the same on BXT by
adding virtual power wells for the same purpose.
Also sanity check the common lane power down ack signal from the PHY. Do
