pci: Enable PCI_MAP_SYSTEM_MEMORY when ARCH_MAP_SYSMEM is not set

For MIPS we are always looking gd->dram in virtual address so
PCI_MAP_SYSTEM_MEMORY should always be enabled.

If in future we ever want to make it physical we have to set
ARCH_MAP_SYSMEM.

          Say Y if base address of system memory is being used as a virtual address
          instead of a physical address (e.g. on MIPS). The PCI core will then remap
