Some new changes to Ibex were not reflected in the documentation. This PR updates it:

  • add new ibex_top parameters
  • add cross-refs throughout the parameter list to explain what they do without duplication
  • add missing ports and their description
  • udpate instantiation snippet updated to match current RTL
  • add missing CSRs
  • add pipeline details for pipeline flush on CSR writes
  • expand explanation on Zcmp behavior concerning interrupts

The CHERIoT documentation is deferred to a separate PR
