When CONFIG_PCI option is not set, the variables
pci_dram_offset, isa_io_base and isa_mem_base are not defined.

Currently, the test is handled in each platform header. This
patch moves the test in io.h once and for all.
    

Be careful with _IO_BASE... I'm not 100% sure some platforms don't need
it set to something else even when PCI is not present.
  

When I saw in  mpc83xx.h and  mpc85xx.h that they still defined them, I
wondered.
But when looking at the code :
    unsigned long isa_io_base     = 0;
    unsigned long isa_mem_base    = 0;
are both defined in pci_{32/64}.c and won't be included if CONFIG_PCI is
not set.
