pci: Enable PCI_MAP_SYSTEM_MEMORY when ARCH_MAP_SYSMEM is not set

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
