PCI: spacemit: Add SpacemiT PCIe host driver
Introduce a driver for the PCIe host controller found in the SpacemiT K1
SoC. The hardware is derived from the Synopsys DesignWare PCIe IP. The
driver supports up to three PCIe ports operating at PCIe link speed up to
5 GT/s. The first port uses a combo PHY, which may be configured for use
for USB3 instead.
