PCI: Fix multiple problems with VIA hardware
This patch is designed to fix: - Disk eating corruptor on KT7 after resume from RAM - VIA IRQ handling - VIA fixups for bus lockups after resume from RAM The core of this is to add a table of resume fixups run at resume time. We need to do this for a variety of boards and features, but particularly we need to do this to get various critical VIA fixups done on resume. The second part of the problem is to handle VIA IRQ number rules which are a bit odd and need special handling for PIC interrupts. Various patches broke various boxes and while this one may not be perfect (hopefully it is) it ensures the workaround is applied to the right devices only. From: Jean Delvare <khali@linux-fr.org> Now that PCI quirks are replayed on software resume, we can safely re-enable the Asus SMBus unhiding quirk even when software suspend support is enabled.
