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. Most of the logic for enabling and disabling the HPD-related interrupts is conditioned on the presence of an EDP panel, but more generically designs that has a downstream drm_bridge (next_bridge) could use this to handle the HPD interrupts, instead of the internal mechanism. So replace the current is_edp-based guards with a check for the presence of next_bridge.
