Subject: powerpc/hotplug-mem: Fix missing endian conversion of aa_index

From: Michael Bringmann <[email protected]>

commit dc421b200f91930c9c6a9586810ff8c232cf10fc upstream.

When adding or removing memory, the aa_index (affinity value) for the memblock must also be converted to match the endianness of the rest of the 'ibm,dynamic-memory' property. Otherwise, subsequent retrieval of the attribute will likely lead to non-existent nodes, followed by using the default node in the code inappropriately.
