Update the register-based memhub to the last specifications

Laurent Petre requested to merge feature/new-register-memhub-magic into main


One commit whose message should well describe the MR:

More specifically, we follow the new system where the magic register is independent of the address table (i.e. always the last register in the GEM block address space) and filled with a status code describing the outcome of the last transaction.
