commit 2cdde91c14ec358087f43287513946d493aef940 upstream.
The tb_dp_port_set_hops() function was incorrectly clearing ADP_DP_CS_1_AUX_RX_HOPID_MASK twice. According to the function's purpose, it should clear both TX and RX AUX HopID fields. Replace the first instance with ADP_DP_CS_1_AUX_TX_HOPID_MASK to ensure proper configuration of both AUX directions.
