powerpc/32: Stop printing Kernel virtual memory layout

Browse source

Printing of Kernel virtual memory layout was added for debug purpose
by commit f637a49e50 ("powerpc: Minor cleanups of kernel virt
address space definitions")

For security reasons, don't display the kernel's virtual memory layout.

Other architectures have removed it through following commits.

Commit 071929dbdd ("arm64: Stop printing the virtual memory layout")
Commit 1c31d4e96b ("ARM: 8820/1: mm: Stop printing the virtual memory layout")
Commit 31833332f7 ("m68k/mm: Stop printing the virtual memory layout")
Commit fd8d0ca256 ("parisc: Hide virtual kernel memory layout")
Commit 681ff0181b ("x86/mm/init/32: Stop printing the virtual memory layout")

Commit 681ff0181b ("x86/mm/init/32: Stop printing the virtual memory
layout") thought x86 was the last one, but in reality powerpc/32 still
had it.

So remove it now on powerpc/32 as well.
