Merge branch 'lorenzo/pci/rockchip'

  - update arm64 defconfig for Rockchip (Shawn Lin)

  - refactor Rockchip code to facilitate both root port and endpoint mode
    (Shawn Lin)

  - add Rockchip endpoint mode driver (Shawn Lin)

* lorenzo/pci/rockchip:
  arm64: defconfig: update config for Rockchip PCIe
  dt-bindings: PCI: rockchip: Add DT bindings for Rockchip PCIe EP driver
  PCI: rockchip: Add EP driver for Rockchip PCIe controller
  dt-bindings: PCI: rockchip: Rename rockchip-pcie.txt to rockchip-pcie-host.txt
  PCI: rockchip: Split out common function to init controller
  PCI: rockchip: Split out rockchip_pcie_parse_dt() to parse DT

* Rockchip AXI PCIe Endpoint Controller DT description
Required properties:
- compatible: Should contain "rockchip,rk3399-pcie-ep"
- reg: Two register ranges as listed in the reg-names property
- reg-names: Must include the following names
- "apb-base"
- "mem-base"
- clocks: Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
- clock-names: Must include the following entries:
- "aclk"
- "aclk-perf"
- "hclk"
- "pm"
- resets: Must contain seven entries for each entry in reset-names.
See ../reset/reset.txt for details.
- reset-names: Must include the following names
- "core"
- "mgmt"
- "mgmt-sticky"
- "pipe"
- "pm"
- "aclk"
- "pclk"
- pinctrl-names : The pin control state names
- pinctrl-0: The "default" pinctrl state
- phys: Must contain an phandle to a PHY for each entry in phy-names.
- phy-names: Must include 4 entries for all 4 lanes even if some of
them won't be used for your cases. Entries are of the form "pcie-phy-N":
where N ranges from 0 to 3.
(see example below and you MUST also refer to ../phy/rockchip-pcie-phy.txt
for changing the #phy-cells of phy node to support it)
- rockchip,max-outbound-regions: Maximum number of outbound regions
Optional Property:
- num-lanes: number of lanes to use
- max-functions: Maximum number of functions that can be configured (default 1).
