Subject: [RFC][PATCH 2/5 v2] drm/bridge: adv7511: Switch to using drm_kms_helper_hotplug_event()

In chasing down a previous issue with EDID probing from calling
drm_helper_hpd_irq_event() from irq context, Laurent noticed
that the DRM documentation suggests that
drm_kms_helper_hotplug_event() should be used instead.

Thus this patch replaces drm_helper_hpd_irq_event() with
drm_kms_helper_hotplug_event().
