This PR adds proper spec-compiant randomization for the exokay signal generated by the random subordinate. It follows the rules specifed in the OBI spec v1.6.0:

  • Only responses to exclusive requests (LR/SC) may signal exokay, other repoonses to other transactions must signal exokay = 0.
  • exokay may not be set if err is set, as {err, exokay} = 2'b11 is reserved.
  • For responses to exclusive requests with no error, provide either:

Additionally, the unused r_queues are removed.
