892fdf15b8 PCI: uniphier-ep: Add NX1 support 
Add basic support for UniPhier NX1 SoC as non-legacy SoC. This includes
a compatible string, SoC-dependent data containing init() and wait()
functions for the controller.

d41584ae86 PCI: uniphier-ep: Add SoC data structure 
Define SoC data structure that includes pci_epc_features, SoC-dependent
callback functions and flags to distinguish the behavior of each SoC.
The callback functions define init() to initialize the controller and
wait() to wait until initialization is completed.

Rename uniphier_pcie_init_ep() to uniphier_pcie_pro5_init_ep() for
initializing PCIe controller implemented in Pro5 SoC. And Pro5 SoC
doesn't have wait() function.

a0fd361db8 PCI: dwc: Move "dbi", "dbi2", and "addr_space" resource setup into common code 
Most DWC drivers use the common register resource names "dbi", "dbi2", and
"addr_space", so let's move their setup into the DWC common code.

This means 'dbi_base' in particular is setup later, but it looks like no
drivers touch DBI registers before dw_pcie_host_init or dw_pcie_ep_init.

8d7e33d681 PCI: uniphier: Add Socionext UniPhier Pro5 PCIe endpoint controller driver 
Add driver for the Socionext UniPhier Pro5 SoC endpoint controller.
This controller is based on the DesignWare PCIe core.

And add "host" to existing controller descriontions for the host controller
in Kconfig.
