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.

Add sideband simulator aux bridge to re-direct sideband message
from aux channel to internal emulation software stack. When this
bridge is connected to DP device, simulator will read ports configuration
from device tree and fake all sideband messages.
