PCI: mvebu: mvebu_pcie_map_registers __iomem fix

Fix the return type of mvebu_pcie_map_registers in the
error path to have __iomem on it. Fixes the following
sparse warning:

drivers/pci/controller/pci-mvebu.c:716:31: warning: incorrect type in return expression (different address spaces)
drivers/pci/controller/pci-mvebu.c:716:31:    expected void [noderef] <asn:2> *
drivers/pci/controller/pci-mvebu.c:716:31:    got void *
