pcie-spear13xx.c sparse warnings

[Bjorn Helgaas <helgaas@xxxxxxxxxx>]

FYI, sparse complains quite about about pcie-spear13xx.c:

  $ make C=2 drivers/pci/controller/dwc/pcie-spear13xx.o
    CHECK   drivers/pci/controller/dwc/pcie-spear13xx.c
  drivers/pci/controller/dwc/pcie-spear13xx.c:73:54: warning: incorrect type in initializer (different address spaces)

  drivers/pci/controller/dwc/pcie-spear13xx.c:100:26:    got unsigned int *
  ...

Any ideas about how to fix these?  I haven't looked into them at all.

I'm building on x86 with CONFIG_COMPILE_TEST=y and CONFIG_OF not set,
so probably not the typical config for this driver.
