msaitoh 714b2af146 Make ppb(4) interrupt support stable:
- Disable all interrupts in the beginning of attach. Without this, interrupt
  storm occurs while cold == 1 on some environment.
- Disable command complete interrput for a while to prevent hangup on some
  enviroment. I'm sorry, I don't know what this bit is :-|
- Check all status bits and return 0 if an interrupt is not for me. It's
  required for INTx. Tested on XEN3_DOM0 because it doesn't support MSI yet.
- Return 1 when a interrupt is processed.
