Generic core VM already prints these information in the log
buffer, hence there is no need for a second print. This just
removes the second print from arch powerpc NUMA init path.

Before the patch:

  $ dmesg | grep "Initmem"

  numa: Initmem setup node 0 [mem 0x00000000-0xffffffff]
  numa: Initmem setup node 1 [mem 0x100000000-0x1ffffffff]
  numa: Initmem setup node 2 [mem 0x200000000-0x2ffffffff]
  numa: Initmem setup node 3 [mem 0x300000000-0x3ffffffff]
  numa: Initmem setup node 4 [mem 0x400000000-0x4ffffffff]
  numa: Initmem setup node 5 [mem 0x500000000-0x5ffffffff]
  numa: Initmem setup node 6 [mem 0x600000000-0x6ffffffff]
  numa: Initmem setup node 7 [mem 0x700000000-0x7ffffffff]
  Initmem setup node 0 [mem 0x0000000000000000-0x00000000ffffffff]
  Initmem setup node 1 [mem 0x0000000100000000-0x00000001ffffffff]
  Initmem setup node 2 [mem 0x0000000200000000-0x00000002ffffffff]
  Initmem setup node 3 [mem 0x0000000300000000-0x00000003ffffffff]
  Initmem setup node 4 [mem 0x0000000400000000-0x00000004ffffffff]
  Initmem setup node 5 [mem 0x0000000500000000-0x00000005ffffffff]
  Initmem setup node 6 [mem 0x0000000600000000-0x00000006ffffffff]
  Initmem setup node 7 [mem 0x0000000700000000-0x00000007ffffffff]

After the patch just the latter set is printed.
