[PATCH] arm64: Make default dma_ops to be noncoherent

[Ritesh Harjani]

Currently arm64 dma_ops is by default made coherent
which makes it opposite in default policy
from arm.

Make default dma_ops to be noncoherent (same
as arm), as currently there aren't any
dma-capable drivers which assumes coherent ops
