Historically the polling value was a hack to reduce the size of the
timer/irq/polling races where IRQs end up unmasked again. Resetting
indicated if a reset was currently progressing (in essence 'don't issue
any more resets for the moment'). At the time at least there were cases
where polling=1 resetting=0 could occur (notably DMA crc error handling).
