Alan Douglas ee12c9efe6 PCI: cadence: Add Power Management ops for host and EP
These PM ops will enable/disable the optional PHYs if present.  The
AXI link-down register in the host driver is now cleared in
cdns_pci_map_bus() since the link-down bit will be set if the PHY has
been disabled. It is not cleared when enabling the PHY, since the
link will not yet be up (e.g. when an EP controller is connected
back-to-back to the host controller and its PHY is still disabled).

Shawn Lin 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.
