[ Upstream commit 2dc0a201d0f59e6818ef443609f0850a32910844 ]
The interrupt affinity scheme used by this driver is incompatible with
multi-MSI as it implies moving the doorbell address to that of another MSI
group. This isn't possible for multi-MSI, as all the MSIs must have the
same doorbell address. As such it is restricted to systems with a single
CPU.

[ Upstream commit e673d697b9a234fc3544ac240e173cef8c82b349 ]
Commit fc54bae28818 ("PCI: iproc: Allow allocation of multiple MSIs")
introduced multi-MSI support with a broken allocation mechanism (it failed
to reserve the proper number of bits from the inner domain). Natural
alignment of the base vector number was also not guaranteed.

[ Upstream commit 1e83130f01b04c16579ed5a5e03d729bcffc4c5d ]
IRQ domain alloc function should return zero on success. Non-zero value
indicates failure.

[ Upstream commit eb7eacaa5b9e4f665bd08d416c8f88e63d2f123c ]
The core interrupt code expects the irq_set_affinity call to update the
effective affinity for the interrupt. This was not being done, so update
iproc_msi_irq_set_affinity() to do so.

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.
