The DisplayPort controller's internal HPD interrupt handling is used for cases where the HPD signal is connected to a GPIO which is pinmuxed into the DisplayPort controller. In other configurations the HPD notification might be delivered by the DRM framework from an associated bridge. This difference is not appropriately represented by the "is_edp" boolean, but is properly represented by the frameworks invocation of the hpd_enable() and hpd_disable() callbacks. Switch the current condition to rely on these callbacks instead. This ensures appropriate handling of the three cases; no bridge connected, a bridge without DRM_BRIDGE_OP_HPD and a bridge with DRM_BRIDGE_OP_HPD.
