PCI: rcar-gen4: Add R-Car Gen4 PCIe controller support for host mode

Add R-Car Gen4 PCIe controller support for host mode.

This controller is based on Synopsys DesignWare PCIe. However, this
particular controller has a number of vendor-specific registers, and as
such, requires initialization code like mode setting and retraining and
so on.

Merge tag 'pci-v6.4-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci

Pull pci updates from Bjorn Helgaas:
"Resource management:

- Add pci_dev_for_each_resource() and pci_bus_for_each_resource()
iterators

PCIe native device hotplug:

- Fix AB-BA deadlock between reset_lock and device_lock

Power management:

- Wait longer for devices to become ready after resume (as we do for
reset) to accommodate Intel Titan Ridge xHCI devices

- Extend D3hot delay for NVIDIA HDA controllers to avoid
unrecoverable devices after a bus reset

Error handling:

- Clear PCIe Device Status after EDR since generic error recovery now
only clears it when AER is native

ASPM:

- Work around Chromebook firmware defect that clobbers Capability
list (including ASPM L1 PM Substates Cap) when returning from
D3cold to D0

Freescale i.MX6 PCIe controller driver:

- Install imprecise external abort handler only when DT indicates
PCIe support

Freescale Layerscape PCIe controller driver:

- Add ls1028a endpoint mode support

Qualcomm PCIe controller driver:

- Add SM8550 DT binding and driver support

- Add SDX55 DT binding and driver support

- Use bulk APIs for clocks of IP 1.0.0, 2.3.2, 2.3.3

- Use bulk APIs for reset of IP 2.1.0, 2.3.3, 2.4.0

- Add DT "mhi" register region for supported SoCs

- Expose link transition counts via debugfs to help debug low power
issues

- Support system suspend and resume; reduce interconnect bandwidth
and turn off clock and PHY if there are no active devices

- Enable async probe by default to reduce boot time

Miscellaneous:

- Sort controller Kconfig entries by vendor"
