Static variable kirin_dw_pcie_ops, of type dw_pcie_ops, is used only
once, when it is assigned to the constant field ops of variable pci
(having type dw_pcie) so kirin_dw_pcie_ops is never modified.
Make it constant to protect it from unintended modification.
Issue found with Coccinelle.

The PCI kirin driver compilation produces the following section mismatch
warning:
WARNING: vmlinux.o(.text+0x4758cc): Section mismatch in reference from
the function kirin_pcie_probe() to the function
.init.text:kirin_add_pcie_port()
The function kirin_pcie_probe() references
the function __init kirin_add_pcie_port().
This is often because kirin_pcie_probe lacks a __init
annotation or the annotation of kirin_add_pcie_port is wrong.
Remove '__init' from kirin_add_pcie_port() to fix 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.
