[DRIVER] DSI-to-LVDS SN65DSI84 bridge: fix initialization sequence

Gianfranco Mariotti requested to merge seco_5.10.110-gm_sn65dsi84 into seco_5.10.110

The SN65DSI84 datasheet states in its initialization sequence description that after power is applied and stable the DSI CLK lanes MUST be in HS state and the DSI data lanes MUST be driven to LP11 state before proceeding to setup the bridge state. After investigating the RK3588 MIPI DSI driver it was found that this required state is attained at the pre_enable callback, so the bridge driver must execute its initialization sequence at the same callback.
