The DP needs to have resumed once the DRM driver calls
drm_atomic_helper_resume, otherwise the DP clock is still disabled when
the DRM core enables the DP bridge.

Would be nice to use device_pm_wait_for_dev to synchronize these
devices, but the DRM device doesn't know what specific implementation
this bridge has.
