[PATCH v4 0/6] Add endpoint driver for Rockchip PCIe controller

[Shawn Lin]

Patch 1 firstly move the whole Rockchip PCIe host driver from
drivers/pci/host to a new folder, driver/pci/rockchip/, and rename
pcie-rockchip.c to pcie-rockchip-host.c. It also updates the
Kconfig/Makefile etc to repect this change.

Then patch 2 and patch 3 are trying to spilt out some common code in
preparation for adding endponit controller driver support.

Patch 4 rename rockchip-pcie.txt to rockchip-pcie-host.txt.

Patch 5 adds endpoint controller driver support as well as the new
documentation, rockchip-pcie-ep.txt, introduced by patch 6.


Changes in v4:
- remove empty line
- keep rockchip's order next to cadence and dwc, but we will
  try to resort it later when reconstructing the directories

Changes in v2:
- remove rockchip,rk3399-pcie-host compatible(Suggested by Rob)
- fix some error handling
Series-changes: 3
- fix all issues suggested by Lorenzo
