Fix sparse build warning:
drivers/pci/controller/pcie-iproc-platform.c:102:33: warning: Using plain integer as NULL pointer
The map_irq member of the struct iproc_pcie takes a function pointer
serving as a callback to map interrupts, therefore we should pass a NULL
pointer to it rather than a integer in the iproc_pcie_pltfm_probe()
function.

default functions")

devm_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_phy_optional_get() is a function that exactly
does what's required here, so use that instead.

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.
