[Intel-gfx] [PATCH 3/5] drm/i915/irq: clarify irq storm related function naming

We'll have three functions:
intel_hpd_irq_storm_detect for detecting irq storms,
intel_hpd_irq_storm_disable for disabling hotplugs after detected storms,
intel_hpd_irq_storm_reenable_work for re-enabling hotplug.
No functional changes.
