This PR introduces several modifications on HeMAiA system. The initial motivation of this PR is to provide functions needed by the future chiplet system, but I later think this may be also good for the current tapeout.

  1. The quadrant, which resides in multiple clusters, has the floating base address so that it can be moved to other socket with different address. As this is specific for chiplet, these signals are grounded to disable this feature.
  2. chip_id signal is added and will be the unique identifier for chip in one package. As this is specific for chiplet, these signals are grounded to disable this feature.
  3. The TLB of the quadrant is removed to save the area.
  4. The inter-quadrant xbar is removed to save the area and reduce the DRAM <-> TCDM latency.
