drm/xe/display: separate d3cold handling from xe_display_pm_runtime_suspend_late()

Browse Source 
Make the special d3cold paths completely separate from the rest of the
runtime pm calls.

The intel_dmc_wl_flush_release_work() call right after
xe_display_pm_suspend_late() might be completely redundant, but this
avoids any functional changes.

Wiggle the comment while at it. It gets duplicated for now, but this
will be addressed in the follow-up.
