Support reading edid through aux channel if panel is connected to aux bus. Extend anx7625_aux_dpcd_trans() to implement aux transfer function: 1. panel is populated in devm_of_dp_aux_populate_ep_devices(), so move anx7625_parse_dt() after. 2. Use pm runtime autosuspend since aux transfer function is called multiple times when reading edid. 3. No-op if aux transfer length is 0.
