Disintegrate asm/system.h for MIPS.

The MIPS implementation of die() forgets to call notify_die() and thus notifiers
registered via register_die_notifier() are not called.  This results in kgdb not
being activated on exceptions.

The only subtlety is that notify_die declares its regs argument w/o const, so
the const had to be removed from mips die() as well.

Using ARRAY_SIZE in these places in arch/mips/sgi-ip22/ip28-berr.c was
bogus, and therefore gets reverted by this patch.
