  SVN rev 180753 on 2008-07-23 09:44:36Z by luoqi
  
  SATA device on some nForce based boards could get confused if MSI is not
  used but MSI to HyperTransport IRQ mapping is enabled, and would act as
  if MSI is turned on, resulting in interrupt loss.
  
  This commit will,
  1. enable MSI mapping on a device only when MSI is enabled for that
     device and the MSI address matches the HT mapping window.
  2. enable MSI mapping on a bridge only when a downstream device is
     allocated an MSI address in the mapping window
