drm/{i915, xe}: add new intel_display_driver_runtime_pm_{enable, disable}()

Browse Source 
Add new high-level functions intel_display_driver_runtime_pm_enable()
and intel_display_driver_runtime_pm_disable() to abstract the low-level
functions intel_display_power_enable() and
intel_display_power_disable(), respectively.

The asymmetry in the "runtime pm enable/disable" and "pm runtime
suspend/etc" naming is intentional, with the latter intended to be
called from the PM hooks.
