drm/bridge: analogix_dp: remove PLL lock check from analogix_dp_config_video

This check is way too late in the DP enable flow. The PLL must be
locked much earlier, before any link training can happen. If the
PLL is unlocked at that point in time there is something seriously
wrong in the enable flow.
