Subject: [PATCH 3/9] arm/PCI: move final fixup quirks from __init to __devinit

The PCI subsystem's final fixups are executed once during boot, after the
pci-device is found.  As long as the system does not support hot-plug,
specifying __init is fine.

With hot-plug, either physically based hot-plug events or pseudo hot-plug
events such as "echo 1 > /sys/bus/pci/rescan", it is possible to remove a
PCI bus during run time and have it rediscovered which will require the
call of the fixups again in order for the device to function properly.

This patch prepares specific quirk(s) for use with hot-plug events.
