MIPS: PCI: Use pci_resource_to_user to map pci memory space properly
[ralf@linux-mips.org: This only matters to Alchemy platforms. On other platforms fixup_bigphys_addr is just an identidy mapping.] Signed-off-by: Wolfgang Grandegger <wg@denx.de> Cc: tiejun.chen <tiejun.chen@windriver.com> Cc: Linux-MIPS <linux-mips@linux-mips.org> Patchwork: https://patchwork.linux-mips.org/patch/1868/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
