RISC-V Debug Specification v1.0 [3.14.22. System Bus Access Control and
Status (`sbcs`, at 0x38)] states in `sbasize` field description:
> Width of system bus addresses in bits. (0 indicates there is no bus
access support.)
Before the patch, the error message did not include the information
about `sbcs.sbasize` being zero wich made it quite undescriptive:
```

In the riscv fork, [1] has disable the debug log during target
polling, with message:
Improve low-level logging.
Now logging is consistent and more readable.
I did remove most logging during riscv_poll() since it clutters
up the log/screen and is not generally helpful.
This is questionable, because if the user enables the debug log,
the messages should all be logged.
Drop the code that overwrites the 'debug_level'.

The cache handling code is written and optimized for dap queuing.
On hla targets it causes a segmentation fault due to uninitialized
AP pointer still set to NULL.
While it's possible to modify the code to cope with hla targets,
this would lower the OpenOCD performance on modern adapters.

The code in an event handler can use the command '$target_name
configure' to add a new event or to remove or modify an existing
event.
Such operation impacts the list of event of the target and also
modify the event itself, causing OpenOCD to access memory already
deallocated or not anymore valid.
Use the safe version of list_for_each_entry() to iterate on the
list of events.
Make a local copy of the current event, to avoid issues if it gets
deallocated.
Use Jim_IncrRefCount() to guarantee that the body of the event
handler don't gets deallocated when the event is removed.
