drm/tegra: dsi: Mark connector hotpluggable
DSI panels can always be hotplugged via the DSI bus' attach/detach infrastructure, so unconditionally mark the connector hotpluggable. While at it, also make sure that when a panel is detached the connector is marked unconnected before calling into the DRM hotplug helpers to reflect the correct state.
