  SVN rev 202624 on 2010-01-19 13:33:31Z by mav
  
  MFC r200814:
  Clear all ports interrupt status bits in single write. Clearing one by one
  causes additional MSIs messages sent if several ports asked for attention
  same time. Time window before clearing is not important, as these interrupts
  are level triggered by interrupt source.
