Modularize the Mobiveil PCIe host driver according to the abstraction of
Root Complex and Endpoint and move it into a new directory in order to
make it easier to reuse the driver functions to add new host drivers for
systems integrating the Mobiveil PCIe GPEX IP.

Cadence core library files may be used by various platform drivers.
Add a new directory "cadence" to group all the Cadence core library files
and the platforms using Cadence core library.

Cadence PCIe host and endpoint IP may be embedded into a variety of
SoCs/platforms. Let's extract the platform related APIs/Structures in the
current driver to a separate file (pcie-cadence-plat.c), such that the
common functionality can be used by future platforms.

This interface driver is a helper driver allows other drivers to
have a common interface with the Hyper-V PCI frontend driver.

commit 9af6bcb11e12 ("PCI: mobiveil: Add Mobiveil PCIe Host Bridge IP
driver") did not add the configuration and build infrastructure to
configure and build the mobiveil controller driver, so at present the
driver code is in the kernel but cannot be compiled.
Add the mobiveil controller driver Kconfig/Makefile infrastructure.

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.
