drm/bridge: anx7625: Support reading edid through aux channel
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.
