Add the ability to have multiple irq priority levels which are not masked by irq_lock() by adding CONFIG_ZERO_LATENCY_LEVELS. If CONFIG_ZERO_LATENCY_LEVELS is set to a value > 1 then multiple zero latency irqs are reserved by the kernel (and not only one). The priority of the zero-latency interrupt can be configured by IRQ_CONNECT. To be backwards compatible the prio argument in IRQ_CONNECT is still ignored and the target prio set to zero if CONFIG_ZERO_LATENCY_LEVELS is 1 (default).
