PCI host drivers have already matched on compatible strings, so checking
device_type is redundant. Also, device_type is considered deprecated for
FDT though we've still been requiring it for PCI hosts as it is useful
for finding PCI buses.

The field pcie_reg_base in struct mobiveil_pcie represents a physical
address so it should be of phys_addr_t type rather than void __iomem*;
this results in the following compilation warnings:

IB_WIN_SIZE is larger than INT_MAX so we need to cast it to u64.

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.
