devm_of_phy_get() can fail for a number of reasons besides probe
deferral. It can for example return -ENOMEM if it runs out of memory as
it tries to allocate devres structures. Propagating only -EPROBE_DEFER
is problematic because it results in these legitimately fatal errors
being treated as "PHY not specified in DT".
What we really want is to ignore the optional PHYs only if they have not
been specified in DT. devm_of_phy_get() returns -ENODEV in this case, so
that's the special case that we need to handle. So we propagate all
errors, except -ENODEV, so that real failures will still cause the
driver to fail probe.

Function dw_pcie_host_init() already initializes the root_bus_nr field
of 'struct pcie_port', so the -1 assignment prior to calling
dw_pcie_host_init() in platform specific driver is not really needed.
Drop it.

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.
