    PCI: Fix multiple problems with VIA hardware · 1597cacb

    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.

    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.
