PCI: hisi: Avoid invalid address space conversions
The sparse checker complains about converting pointers between address
spaces. The pci_config_window.priv pointer is a generic void *, but
hisi_pcie_map_bus() needs a void __iomem *.
This isn't a problem in other drivers because they store the __iomem
pointer in a driver struct. Add a trivial struct hisi_pcie to avoid the
warning.
The sparse warning looks like this:
$ make C=2 drivers/pci/controller/
drivers/pci/controller/dwc/pcie-hisi.c:61:37: warning: incorrect type in initializer (different address spaces)
drivers/pci/controller/dwc/pcie-hisi.c:61:37: expected void [noderef] __iomem *reg_base
drivers/pci/controller/dwc/pcie-hisi.c:61:37: got void *priv
