The ALi loses some state if it goes into D3. Unfortunately even with the
chipset documents I can't figure out how to restore some bits of it.

The VIA one saves/restores apparently fine but the ACPI _GTM methods break
on some platforms if we do this and this causes cable misdetections.

These are both effectively regressions as historically nothing matched the
devices and then decided not to bind to them. Nowdays something is binding
to all sorts of devices and a result they get dumped into D3.

I found no references to SMBus in ACPI DSDT disassembly on my laptop
so this should be safe.

Some BIOSes hide 'overflow' device (dev #6) for i82875P/PE chipsets.
The same happens for i82865P/PE. Add a quirk to enable this device.
This allows i82875 EDAC driver to bind to chipset's dev #6 and not
dev #0 as the latter is used by AGP driver.

On my laptop (i82865P based) ACPI code is disabling this device
again in \_SB.PCI0._CRS method (called at least at PNP init time).
This can be easily worked around by patching DSDT.

Addition of one unknown subsystem identifier to the quirks handler for
chipset i82855GM_HB on notebook Asus A6L. This exposes the otherwise
hidden SMBus controller within the south bridge ICH4-M.

The current quirk doesn't include all 82576 device IDs.  This update
resolves that.

Without this patch, Broadcom BCM5906 Ethernet controllers set up via MSI
cause the machine to hang.  Tejun agreed that the best is to blacklist
the whole chipset and after adding it, seeing the other VIA quirks
disabling MSI, this very much looks like the right way.

This patch fixes breakage of of enable_cnt in quirk_resource_alignment.

Currently, quirk_resource_alignment calls pci_disable_device.
pci_disable_device decrements enable_cnt, so that enable_cnt becomes -1.

The patch disables memory decoding, writing command register directly.
So enable_cnt is not broken.

If BIOS doesn't allocate resources for the SR-IOV BARs, zero the Flash
BAR and program the SR-IOV BARs to use the old Flash Memory Space.
