powerpc/mm: don't display empty early ioremap area 

On the 8xx, the layout displayed at boot is:

[    0.000000] Memory: 121856K/131072K available (5728K kernel code, 592K rwdata, 1248K rodata, 560K init, 448K bss, 9216K reserved, 0K cma-reserved)
[    0.000000] Kernel virtual memory layout:
[    0.000000]   * 0xffefc000..0xffffc000  : fixmap
[    0.000000]   * 0xffefc000..0xffefc000  : early ioremap
[    0.000000]   * 0xc9000000..0xffefc000  : vmalloc & ioremap
[    0.000000] SLUB: HWalign=16, Order=0-3, MinObjects=0, CPUs=1, Nodes=1

Remove display of an empty early ioremap.
