bbc: Re-implemented ROM slots to be able to handle non-standard ROM devices, and added support for:
- 32K ROM slots in B+ and Master series.
- PALPROM carrier boards from Computer Concepts, Watford Electronics, etc.
- Real Time Clock ROM devices from Solidisk and PMS.
- UserRAM sideways RAM from Acorn User.
- MRM E00 DFS.
