The kgdb (in multiple places) and traps code developed pretty much
identical checks for how to access different regions of the Blackfin
memory map, but each wasn't 100%, so unify them to avoid duplication,
bitrot, and bugs with edge cases.

The kgdb_ebin2mem() was decrementing the count variable to do parsing, but
then later still tries to use it based on its original meaning. So leave
it untouched and use a different variable to walk the memory.

The Blackfin kgdb code was all passing back positive errno values when it
really should have been using negative errno values.

Hardware breakpoint doesn't always work in kgdb. It works at the first
two times, but if you repeatedly trigger that hardware breakpoint, it
would slip over that point once in two times.
Fix it by always setting hw bp skip to 0. gdb does skip after hw bp trap.
