SVN rev 200814 on 2009-12-21 21:27:56Z by mav
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.
