drm/bridge: tc358768: Set pre_enable_prev_first for reverse order

Enable the pre_enable_prev_first flag on the tc358768 bridge to reverse
the pre-enable order, calling bridge pre_enable before panel prepare.
This ensures the bridge is ready before sending panel init commands in
the case of panels sending init commands in panel prepare function.
