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.

devm_of_pci_get_host_bridge_resources()
of_pci_get_host_bridge_resources() allocates the resource structures it
fills dynamically, but none of its callers care to release them so far.
Rather than requiring everyone to do this explicitly, convert the existing
function to a managed version.

The functions in linux/of_pci.h are primarily used by host bridge
drivers, so they can be private to drivers/pci/.
The remaining functions are still used mostly in host bridge drivers
that still live in arch specific code. Hopefully someday, those will get
moved into drivers/pci as well.

There is an obvious typo issue in the definition of the PCIe maximum
read request size: a bit shift is directly used as a value, while it
should be used to shift the correct value.

The Aardvark has two interrupts sets:
- first set is bit[23:16] of PCIe ISR 0 register(RD0074840h)
- second set is bit[11:8] of PCIe ISR 1 register(RD0074848h)
Only one set should be used, while another set should be masked.
The second set, ISR1, is more advanced, the Legacy INT_X status bit is
asserted once Assert_INTX message is received, and de-asserted after
Deassert_INTX message is received which matches what the driver is
currently doing in the ->irq_mask() and ->irq_unmask() functions.
The ISR0 requires additional work to deassert the interrupt, which the
driver does not currently implement, therefore it needs fixing.
Update the driver to use ISR1 register set, fixing current
implementation.

The PCI configuration space read/write functions were special casing
the situation where PCI_SLOT(devfn) != 0, and returned
PCIBIOS_DEVICE_NOT_FOUND in this case.
However, while this is what is intended for the root bus, it is not
intended for the child busses, as it prevents discovering devices with
PCI_SLOT(x) != 0. Therefore, we return PCIBIOS_DEVICE_NOT_FOUND only
if we're on the root bus.

struct pci_host_bridge gained hooks to map/swizzle IRQs, so that the IRQ
mapping can be done automatically by PCI core code through the
pci_assign_irq() function instead of resorting to arch-specific
implementation callbacks to carry out the same task which force PCI host
bridge drivers implementation to implement per-arch kludges to carry out a
task that is inherently architecture agnostic.
Commit 769b461fc0c0 ("arm64: PCI: Drop DT IRQ allocation from
pcibios_alloc_irq()") was assuming all PCI host controller drivers had been
converted to use ->map_irq(), but that wasn't the case: pci-aardvark had
not been converted. Due to this, it broke the support for legacy PCI
interrupts when using the pci-aardvark driver (used on Marvell Armada 3720
platforms).
In order to fix this, we make sure the ->map_irq and ->swizzle_irq fields
of pci_host_bridge are properly filled in.

The introduction of pci_scan_root_bus_bridge() provides a PCI core API to
scan a PCI root bus backed by an already initialized struct pci_host_bridge
object, which simplifies the bus scan interface and makes the PCI scan root
bus interface easier to generalize as members are added to the struct
pci_host_bridge.
Convert PCI aardvark host code to pci_scan_root_bus_bridge() to improve the
PCI root bus scanning interface.

On ARM/ARM64 architectures, PCI IO ports are emulated through memory mapped
IO, by reserving a chunk of virtual address space starting at PCI_IOBASE
and by mapping the PCI host bridge's memory address space driving PCI IO
cycles to it.
PCI host bridge drivers that enable downstream PCI IO cycles map the host
bridge memory address responding to PCI IO cycles to the fixed virtual
address space through the pci_remap_iospace() API.
This means that if the pci_remap_iospace() function fails, the
corresponding host bridge PCI IO resource must be considered invalid, in
that there is no way for the kernel to actually drive PCI IO transactions
if the memory addresses responding to PCI IO cycles cannot be mapped into
the CPU virtual address space.
The PCI aardvark host bridge driver does not remove the PCI IO resource
from the host bridge resource windows if the pci_remap_iospace() call
fails; this is an actual bug in that the PCI host bridge would consider the
PCI IO resource valid (and possibly assign it to downstream devices) even
if the kernel was not able to map the PCI host bridge memory address
driving IO cycle to the CPU virtual address space (ie pci_remap_iospace()
failures).
Fix the PCI host bridge driver pci_remap_iospace() failure path, by
destroying the PCI host bridge PCI IO resources retrieved through firmware
when the pci_remap_iospace() function call fails, therefore preventing the
kernel from adding the respective PCI IO resource to the list of PCI host
bridge valid resources, fixing the issue.
