irqchip/gicv3-its: numa: Enable workaround for Cavium thunderx erratum 23144

[ Upstream commit fbf8f40e1658cb2f17452dbd3c708e329c5d27e0 ]

The erratum fixes the hang of ITS SYNC command by avoiding inter node
io and collections/cpu mapping on thunderx dual-socket platform.

This fix is only applicable for Cavium's ThunderX dual-socket platform.
