The pci_host_bridge struct already has a pointer to its pci_bus, so
let's convert the one user to use the bridge struct and remove the
private 'root_bus' pointer.

Now that there are no more .scan_bus() callbacks, we can remove it and just

TI keystone is the only Designware driver using .scan_bus(). This
function pointer is the only thing preventing the Designware driver from
using pci_host_probe(). Let's use the pci_ops.add_bus hook instead.

Now that all the platforms with custom config access handling define
their own pci_ops, let's split the default config accessors to use
different pci_ops for root and child buses. With this, we can use the
generic config accessors. The child bus accesses mainly require a
.map_bus() hook to reconfigure the iATU on each config space access.

Move code which belongs to link training (delays and resets) into
advk_pcie_train_link() function, so everything related to link training,
including timings is at one place.
After experiments it can be observed that link training in aardvark
hardware is very sensitive to timings and delays, so it is a good idea to
have this code at the same place as link training calls.
This patch does not change behavior of aardvark initialization.

Add support for Versal CPM as Root Port.
The Versal ACAP devices include CCIX-PCIe Module (CPM). The integrated
block for CPM along with the integrated bridge can function as PCIe Root
Port.
Bridge error and legacy interrupts in Versal CPM are handled using Versal
CPM specific interrupt line.

The majority of DT based host drivers use the default .map_irq() and
.swizzle_irq() functions, so let's initialize the function pointers to
the default and drop setting them in the host drivers.
Drivers like iProc which don't support legacy interrupts need to set
.map_irq() back to NULL.

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.

There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq() or
platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.
This change is as per suggestions from Coccinelle, e.g.,
drivers/pci/controller/dwc/pcie-armada8k.c:252:2-9: line 252 is
redundant because platform_get_irq() already prints an error
