Stepping in the maskisr auto mode sets breakpoint to step over interrupt
service tasks. If the device has FPB rev 1, setting hard breakpoint
is impossible on address over 0x1fffffff.
Use soft type breakpoint for adresses over 0x1fffffff if FPB is rev 1.
This may eventually fail if the code memory is not writeable, but there
is nothing to do in such case.
