Update physical memory and address translation for MMIO.
- Assume for now that atomic accesses are only to memory regions, to leave
their effects unchanged.
- The top-level mem_read and mem_write functions for physical memory now
have rreg and wreg effects due to MMIO (due to reads/writes to device registers).
It would be nice to have a separate construct for non-CPU-register state to avoid
polluting the footprint.
- Assume for now that page-table walks access physical memory regions only, and
not MMIO regions. Leave a fixme note there to address this later, perhaps when
PMP/PMA is added.
