Current code is setting only intel_crtc_state->has_panel_replay in panel
replay case. There are lots of stuff behind intel_crtc_state->has_psr that
is needed for panel replay as well. Instead of converting each check to
has_psr || has_panel_replay set has_psr in case of panel replay as
well. Code can then differentiate between psr and panel replay by using
intel_crtc_state->has_panel_replay.

Currently intel_connector_info(), which prints the per-connector
output for i915_display_info, just bails out early if the connector
doesn't have a current encoder. That leads to very confusing output
where some of your connected (and properly detected) outputs appear
to have no enumerated modes.
Get rid of the encoder stuff and just rely on the connector itself
so that the output is always consistent.

Currently we can't change MBUS join status without doing a modeset,
because we are lacking mechanism to synchronize those with vblank.
However then this means that we can't do a fastset, if there is a need
to change MBUS join state. Fix that by implementing such change.
We already call correspondent check and update at pre_plane dbuf update,
so the only thing left is to have a non-modeset version of that.
If active pipes stay the same then fastset is possible and only MBUS
join state/ddb allocation updates would be committed.
The full mbus/cdclk sequence will look as follows:
1. disable pipes
2. increase cdclk if necessary
2.1 reprogram cdclk
2.2 update dbuf tracker value
3. enable mbus joining if necessary
3.1 update mbus_ctl
3.2 update dbuf tracker value
4. reallocate dbuf for planes on active pipes
5. disable mbus joining if necessary
5.1 update dbuf tracker value
5.2 update mbus_ctl
6. enable pipes
7. decrease cdclk if necessary
7.1 update dbuf tracker value
7.2 reprogram cdclk
And in order to keep things in sync we need:
Step 2:
- mbus_join == old
- mdclk/cdclk ratio == new
Step 3:
- mbus_join == new
- mdclk/cdclk ratio == old when cdclk is changing in step 7
- mdclk/cdclk ratio == new when cdclk is changing in step 2
Step 5:
- mbus_join == new
- mdclk/cdclk ratio == old when cdclk is changing in step 7
- mdclk/cdclk ratio == new when cdclk is changing in step 2
Step 7:
- mbus_join == new
- mdclk/cdclk ratio == new
v2: - Removed redundant parentheses(Ville Syrjälä)
- Constified new_crtc_state in intel_mbus_joined_pipe(Ville Syrjälä)
- Removed pipe_select variable(Ville Syrjälä)

The current cdclk/mbus programming sequence is as follows:
1. intel_set_cdclk_pre_plane_update()
2. update_mbus_pre_enable()
3. intel_set_cdclk_post_plane_update()
when the actual mdclk/cdclk programming is postponed to
intel_set_cdclk_post_plane_update() we must keep using
the old mdclk/cdclk ratio during update_mbus_pre_enable().
This guarantees the programmed ratio matches the rest of
the hardware state (mdlk/cdclk/mbus joining).

Currently we only consider the relationship of the
old and new CDCLK frequencies when determining whether
to do the repgramming from intel_set_cdclk_pre_plane_update()
or intel_set_cdclk_post_plane_update().
It is technically possible to have a situation where the
CDCLK frequency is decreasing, but the voltage_level is
increasing due a DDI port. In this case we should bump
the voltage level already in intel_set_cdclk_pre_plane_update()
(so that the voltage_level will have been increased by the
time the port gets enabled), while leaving the CDCLK frequency
unchanged (as active planes/etc. may still depend on it).
We can then reduce the CDCLK frequency to its final value
from intel_set_cdclk_post_plane_update().
In order to handle that correctly we shall construct a
suitable amalgam of the old and new cdclk states in
intel_set_cdclk_pre_plane_update().
And we can simply call intel_set_cdclk() unconditionally
in both places as it will not do anything if nothing actually
changes vs. the current hw state.

Currently we always reprogram CDCLK from the
intel_set_cdclk_pre_plane_update() when using squash/crawl.
The code only works correctly for the cd2x update or full
modeset cases, and it was simply never updated to deal with
squash/crawl.
If the CDCLK frequency is increasing we must reprogram it
before we do anything else that might depend on the new
higher frequency, and conversely we must not decrease
the frequency until everything that might still depend
on the old higher frequency has been dealt with.
Since cdclk_state->pipe is only relevant when doing a cd2x
update we can't use it to determine the correct sequence
during squash/crawl. To that end introduce cdclk_state->disable_pipes
which simply indicates that we must perform the update
while the pipes are disable (ie. during
intel_set_cdclk_pre_plane_update()). Otherwise we use the
same old vs. new CDCLK frequency comparsiong as for cd2x
updates.
The only remaining problem case is when the voltage_level
needs to increase due to a DDI port, but the CDCLK frequency
is decreasing (and not all pipes are being disabled). The
current approach will not bump the voltage level up until
after the port has already been enabled, which is too late.
But we'll take care of that case separately.
