[patch] PCI: disable the MSI of AMD RS690

[Shane Huang]

This patch recover Tejun's commit
4be8f906435a6af241821ab5b94b2b12cb7d57d8
 because there is one MSI bug on RS690+SB600 board which will lead to
boot failure. This bug is NOT same as the one in SB700 SATA controller,
quirk_msi_intx_disable_bug does not work to SB600. Disablement the MSI
of RS690 is the workaround.

Since there is some word wrapping problem with my mail client MS outlook
if I copy the patch into the text, so I'll also attach the patch as an
attachment. Please check it.
