699ca30162 PCI: xilinx: Check for __get_free_pages() failure
If __get_free_pages() fails, return -ENOMEM to avoid a NULL pointer
dereference.

de17c52002 PCI: Remove unnecessary check of device_type == pci
PCI host drivers have already matched on compatible strings, so checking
device_type is redundant. Also, device_type is considered deprecated for
FDT though we've still been requiring it for PCI hosts as it is useful
for finding PCI buses.

8c3f9bd851 PCI: xilinx: Add missing of_node_put()
The call to of_get_next_child() returns a node pointer with refcount
incremented thus it must be explicitly decremented here after the last
usage.

6e0832fa43 PCI: Collect all native drivers under drivers/pci/controller/
Native PCI drivers for root complex devices were originally all in
drivers/pci/host/.  Some of these devices can also be operated in endpoint
mode.  Drivers for endpoint mode didn't seem to fit in the "host"
directory, so we put both the root complex and endpoint drivers in
per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc.

These per-device directories contain trivial Kconfig and Makefiles and
clutter drivers/pci/.  Make a new drivers/pci/controllers/ directory and
collect all the device-specific drivers there.

No functional change intended.
