Since we're about to be using drm_dbg_*() throughout the DP helpers, we'll need to be able to access the DRM device in the dual mode DP helpers as well. Note however that since drm_dp_dual_mode_detect() can be called with DDC adapters that aren't part of a drm_dp_aux struct, we need to pass down the drm_device to these functions instead of using drm_dp_aux.
