ignore soft bp except when single step except occurs.
Narrow the condition to ignore soft bp.
If soft bp occurs in the single step handler or the soft bp handler,
return immediately. This could happen when gdb client set soft bps in
kernel code that in the path of kgdb core code.

early serial init also utilizes the peripheral request api - however
at this point bfin_gpio_init didn't allocate memory for the labels.
So we always have two zombies (allocated pin functions without labels)

This happens before the initcalls - We now allocate memory statically.
Define MAX_RESOURCES individually for each cpu.
