PCI: quirk_e100_interrupt() called too early



quirk_e100_interrupts() is called after PCI controller is initialized
and before PCI bus enumeration is performed. On some powerpc platforms
which modify PCI controller configuration and set different MEM and IO
windows than those set by firmware quirk_e100_interrupt() is causing
kernel panic as it tries to read from device BAR0 offets which at this
time points to a invalid PCI window (set by firmware).

This patch delays the quirk_100_interrupt() to pci_fixup_final phase,
which happens after bus enumeration and before PCI enable and
device driver initialization.
