Ville Syrjälä 3aecee90ac drm/i915/cdclk: Fix CDCLK programming order when pipes are active 
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.

v2: Don't break the "must disable pipes case"
v3: Keep the on stack 'pipe' for future use
