Denis Efremov c9c13ba428 PCI: Add PCI_STD_NUM_BARS for the number of standard BARs
Code that iterates over all standard PCI BARs typically uses
PCI_STD_RESOURCE_END.  However, that requires the unusual test
"i <= PCI_STD_RESOURCE_END" rather than something the typical
"i < PCI_STD_NUM_BARS".

Add a definition for PCI_STD_NUM_BARS and change loops to use the more
idiomatic C style to help avoid fencepost errors.

Gustavo Pimentel d3c70a98d7 PCI: Update xxx_pcie_ep_raise_irq() and pci_epc_raise_irq() signatures
Change {cdns, dra7xx, artpec6, dw, rockchip}_pcie_ep_raise_irq() and
pci_epc_raise_irq() signature, namely the interrupt_num variable type
from u8 to u16 to accommodate 2048 maximum MSI-X interrupts.

Shawn Guo 84b8821955 PCI: artpec6: Drop unnecessary root_bus_nr setting
Function dw_pcie_host_init() already initializes the root_bus_nr field
of 'struct pcie_port', so the -1 assignment prior to calling
dw_pcie_host_init() in platform specific driver is not really needed.
Drop it.

Shawn Lin 6e0832fa43 PCI: Collect all native drivers under drivers/pci/controller/
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.
