commit ff1e8fb68ea0 ("drm/bridge: analogix-anx78xx: Avoid drm_dp_link helpers")
changed the link training logic to remove use of drm_dp_link helpers.
However the new logic stores the maximum link rate in a u8, overflowing
it.
This commit changes the logic to store the bw code directly, avoiding any
overflows.
