[RFC 0/3] ARM: Allow PCI host drivers to be unloaded

Hi,
This is a set of experimental patches that allow ARM PCI host drivers to
be unloaded. The first two patches enhance the ARM core PCI code with
functions to tear down fixed PCI I/O mappings and unregister a PCI host
bridge. The third patch uses the new functionality to allow the Tegra
PCIe driver to unbind from a device.
I'm sending this as an RFC because, while I've been able to successfully
unbind and rebind the Tegra PCIe driver and verifying that a NIC
connected via PCIe still works after each new probe, I haven't fully
investigated yet whether there may be memory leaks due to missing
cleanup.
