bsps/arm: Adjust stacks for ARMv4
Reduce non-IRQ stacks to size zero. All non-IRQ stacks overlap now the
IRQ stack. This is all right since the SVC stack is used only during
startup and here interrupts are disabled. The other exception stacks
lead to a system termination by default, so we can here also use the IRQ
stack since interrupts are disabled on exception entry.
