drm/bridge: analogix_dp: Support to get &analogix_dp_device.plat_data and &analogix_dp_device.aux

Browse Source 
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.
