---------------------------
misc: Clean up and complete the gem5<->SystemC-TLM bridge [5/10]

The current TLM bridge only provides a Slave Port that allows the gem5
world to send request to the SystemC world. This patch series refractors
and cleans up the existing code, and adds a Master Port that allows the
SystemC world to send requests to the gem5 world.

This patch:
 * Introduce transactor modules that represent the gem5 ports in the
 * SystemC world.
 * Update the SimControl module and let it keep track of the gem5 ports.
