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

Browse source

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.
