Igor Mammedov 99d09dd328 pcihp: make pci_read() mmio calback compatible with legacy ACPI hotplug ... due to recent change introduced by: "pcihp: reduce number of device check events" 'up' field is cleared right after it's read. This is incompatible with legacy BIOS ACPI code where PCNF ACPI method reads this field 32 times. To make pci_read mmio callback compatible with legacy 'up' behavior, pcihp code will need to know in which mode it runs add 'legacy_piix' field to AcpiPciHpState structure and alter register behavior accordingly.
