drm/i915/display: Remove TGL DC3CO support

Browse source

Remove all Tiger Lake DC3CO-related functions from intel_psr.c and
intel_display_power_well.c, as the feature is not enabled and not used.
Also remove the TGL/DG1 DC3CO count debugfs entry from intel_dmc.c,
as DC3CO is not active on those platforms. A new debugfs entry for
Xe3LP will be added in a subsequent patch.

Remove the unused dc3co_exitline field from struct intel_psr and
struct intel_crtc_state, along with the corresponding EXITLINE register
read in intel_psr_get_config().

Changes in v2:
- Squash "Remove unused PSR dc3co_exitline field" and
  "Remove unused dc3co_exitline from crtc_state" into this patch
