arm64/numa: Drop duplicate message



When booting linux on a system without CONFIG_NUMA enabled, the
following messages are printed during boot -

NUMA: Faking a node at [mem 0x0000000000000000-0x00000083ffffffff]
NUMA: Adding memblock [0x8000000000 - 0x8000e7ffff] on node 0
NUMA: Adding memblock [0x8000e80000 - 0x83f65cffff] on node 0
NUMA: Adding memblock [0x83f65d0000 - 0x83f665ffff] on node 0
NUMA: Adding memblock [0x83f6660000 - 0x83f676ffff] on node 0
NUMA: Adding memblock [0x83f6770000 - 0x83f678ffff] on node 0
NUMA: Adding memblock [0x83f6790000 - 0x83fb82ffff] on node 0
NUMA: Adding memblock [0x83fb830000 - 0x83fbc0ffff] on node 0
NUMA: Adding memblock [0x83fbc10000 - 0x83fbdfffff] on node 0
NUMA: Adding memblock [0x83fbe00000 - 0x83fbffffff] on node 0
NUMA: Adding memblock [0x83fc000000 - 0x83fffbffff] on node 0
NUMA: Adding memblock [0x83fffc0000 - 0x83fffdffff] on node 0
NUMA: Adding memblock [0x83fffe0000 - 0x83ffffffff] on node 0
NUMA: Initmem setup node 0 [mem 0x8000000000-0x83ffffffff]
NUMA: NODE_DATA [mem 0x83fffec500-0x83fffedfff]

The information is then duplicated by core kernel messages right after
the above output.

Initmem setup node 0 [mem 0x0000008000000000-0x00000083ffffffff]

Remove the duplication of memblock layout information printed during
boot by dropping the messages from arm64 numa initialisation.
