With the special d3cold handling in xe runtime suspend/resume separated,
unify the non-d3cold paths with i915. There are multiple changes here at
once that probably wouldn't make much sense to split out further.

Add the call to intel_display_driver_pm_runtime_suspend(), which, for
the time being, is a no-op. The intel_hpd_poll_enable() is called later.

Add the call to intel_display_driver_pm_runtime_suspend_late(), which
starts calling intel_display_power_runtime_suspend() and
intel_opregion_notify_adapter(). Deep down, the former should take care
of intel_dmc_wl_flush_release_work(), allowing us to drop the extra call
in xe_display_pm_runtime_suspend_late(). The intel_hpd_poll_enable()
call is also done here, postponed from the previous location in
xe_display_pm_runtime_suspend().

Add the call to intel_display_driver_pm_runtime_resume_early(), which
contains the intel_display_power_runtime_resume() and
intel_opregion_notify_adapter() counterparts to the calls in
intel_display_power_runtime_suspend_late().

Finally, intel_display_driver_pm_runtime_resume() replaces the direct
calls to intel_hpd_init(), intel_hpd_poll_disable(), and
skl_watermark_ipc_update(). (The hotplug poll enable/disable calls are
asymmetric.)

v2:
- Rebase, move placement of the calls
