PCI: avoid boot interrupt quirk for AMD 813x B1 devices 

AMD 813x rev. B1 (like rev. B2) devices generate no interrupts if
quirk_disable_amd_813x_boot_interrupt is executed, add an exception.
http://bugzilla.kernel.org/show_bug.cgi?id=14159



Patch also adds missing cases for DECLARE_PCI_FIXUP_RESUME and
DECLARE_PCI_FIXUP_FINAL calls to quirk_disable_amd_813x_boot_interrupt.
