devm_add_action_or_reset() is a helper function which internally calls
devm_add_action(). If the devm_add_action() fails, it will execute the
action mentioned and return the error code.
Use devm_add_action_or_reset() to reduce source code size (avoid writing
the action twice) and reduce the likelihood of bugs.

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.

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.
