This series adds PCIe controller driver for Unisoc SoCs.
This controller is based on DesignWare PCIe IP.

Changes from v1:
1) Test this patch on top of Rob Herring's 40 part series of DWC clean-ups:
   https://lore.kernel.org/linux-pci/20200821035420.380495-1-robh@kernel.org/

2) Delete empty function

3) Document property "sprd,pcie-poweron-syscons" and
   'sprd,pcie-poweroff-syscons'

4) Delete runtime suspend/resume function

5) Add COMPILE_TEST which CONFIG_PCIE_SPRD depends on

Changes from v2:
1) Change RC mode to host mode in drivers/pci/controller/dwc/Kconfig

2) Change Signed-off-by from Billows Wu to Hongtao Wu
