drm: panel: boe-bf060y8m-aj0: Enable prepare_prev_first

Browse Source 
Enable prepare_prev_first flag for BF060Y8M-AJ0 panel so that the
previous controller should be prepared first before the prepare for
the panel is called.

This makes sure that the previous controller, likely to be a DSI host
controller should be initialized to LP-11 before the panel is powered up.
