Draft: Consolidate the (lp)GBT(x) handling

Laurent Petre requested to merge feature/consolidate-gbt into main


This MR aims at improving the handling of the GBT chips, in the most general sense:

  • Link status monitoring
  • Robustness of the IC communication
  • Availability of IC reads and writes, including masked writes
  • Support for the GBTx, lpGBT v0, and lpGBT v1
  • Rebase and inclusion of MR opened since too long (at first !241)
  • Optionally support for VTRx+ configuration
