Add below new APIs to dp_mst_sim to allow more controls from other dp modules: dp_sim_create_bridge: create dp_sim bridge simulator. dp_sim_destroy_bridge: destroy dp_sim bridge simulator. dp_sim_set_sim_mode: enable/disable simulation mode. dp_sim_set_mst_mode: update dp-mst simulation mode. dp_sim_update_port_status: update dp-mst port status in simulator. dp_sim_update_port_edid: update dp-sst/mst port edid in simulator. dp_sim_write_dpcd_reg: update dpcd register in simulator. dp_sim_read_dpcd_reg: read dpcd register from simulator. With the new functions dp_debug can move its internal debug function to dp aux simulator, and dp_display can switch between simulation mode and physical mode dynamically.
