Convert calls to platform_get_resource() and devm_ioremap_resource()
into a single call to devm_platform_get_and_ioremap_resource(), to
simplify the code.
This new helper added in commit 890cc39a8799 ("drivers: provide
devm_platform_get_and_ioremap_resource()") does what both of the
other separate functions do.

Add Renesas RZ/N1 SOC family support to the Renesas R-Car Gen2 PCI bridge
driver.
The Renesas RZ/N1 SOC internal PCI bridge is compatible with the one in the
R-Car Gen2 family.
Tested with the RZ/N1D (R9A06G032) SOC.

Rename struct rcar_pci_priv to rcar_pci to match the convention of
<driver>_pci. No functional change intended.

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Now that pci_parse_request_of_pci_ranges() callers just setup
pci_host_bridge.windows and dma_ranges directly and don't need the bus
range returned, we can just initialize them when allocating the
pci_host_bridge struct.
With this, pci_parse_request_of_pci_ranges() becomes a static function.

The rcar-gen2 host driver still uses the old Arm PCI setup function
pci_common_init_dev(). Let's update it to use the modern
devm_pci_alloc_host_bridge(), pci_parse_request_of_pci_ranges() and
pci_host_probe() functions.

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.
