x86, pci: detect end_bus_number according to acpi/e820 reserved, v2
Jack Howarth reported that 2.6.26-rc9-git9 doesn't boot on MacBookPro2.
the reason is a faulty BIOS update that reportes faulty resources.
Nevertheless it's possible for Linux to be more resolent about this
situation (and similar situations) and work around this bug, by
cross-checking the mmconf range against the e820 table and ACPI resources.
Change the mconf bus range from [0,0xff] to to [0, 0x3f]
to match range [0xf0000000, 0xf4000000) in e820 tables.
