Instead of modifying intel_panel in lvds_init_connector/dsi_init/
edp_init_connector, making changes to move intel_panel->downclock_mode
initialization to intel_panel_init()

v2: Jani's review comments incorporated
Removed downclock_mode local variable in dsi_init and
edp_init_connector

Please don't add extra local variables just to pass NULL to
intel_panel_init(). You can change this if/when we actually start using
the downclock_mode.
