Add two new functions: one to find &analogix_dp_device.plat_data via &drm_dp_aux, and the other to get &analogix_dp_device.aux. Both of them serve for the function of getting panel from DP AUX bus, which is why they are included in a single commit.

Nit: it should be enough to fordward-declare struct drm_dp_aux here. Nevertheless: Reviewed-by: Dmitry Baryshkov <redacted>
