drm/bridge: tc358764: Enable pre_enable_prev_first flag

Enable the drm bridge pre_enable_prev_first flag so that the
previous bridge pre_enable should be called first before the
pre_enable for the tc358764 bridge is called.

This makes sure that the previous bridge should be initialized
properly before the tc358764 bridge is powered up.
