[ Upstream commit f316a2b53cd7f37963ae20ec7072eb27a349a4ce ]
hook_fault_code() is an ARM32 specific API for hooking into data abort.
AM65X platforms (that integrate ARM v8 cores and select CONFIG_ARM64 as
arch) rely on pci-keystone.c but on them the enumeration of a
non-present BDF does not trigger a bus error, so the fixup exception
provided by calling hook_fault_code() is not needed and can be guarded
with CONFIG_ARM.

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.
