Message:

Modifications in vci_mem_cache:

• Bugfix in req_distance function used to compute manhattan distance between requests coordinates and self global coordinates.

• New constructor parameters for vci_mem_cache:
  1. x_self : X self coordinate
  2. y_self : Y self coordinate

This parameter are used for instrumentation

• Remove cc_global_id constructor parameter:

This parameter was the mem_cache coherence srcid. This srcid is not
used by the L1 caches because they take the mem cache global id from
the msb of nline to invalidate (CLEANUP) or to update (MULTIACK)

As the constructor parameters has been changed, the platform using the
mem cache must be changed accordingly. Therefore, the tsar_generic_xbar and
the tsar_generic_iob platforms were updated.
