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.
