[PATCH v6 21/22] drm/rockchip: dw_hdmi_qp: Switch to dw_hdmi_qp_hpd_notify()

[Cristian Ciocaltea <cristian.ciocaltea@collabora.com>]

Switch from drm_helper_hpd_irq_event(), which polls all connectors, to
the recently introduced dw_hdmi_qp_hpd_notify() helper, which runs the
detect cycle only on the affected connector.

This avoids unnecessary work and redundant detect calls on unrelated
connectors.
