arm: select the dma-noncoherent symbols for all swiotlb builds
We need to provide the arch hooks for non-coherent dma-direct
and swiotlb for all swiotlb builds, not just when LPAS is enabled.
Without that the Xen build that selects SWIOTLB indirectly through
SWIOTLB_XEN fails to build.
Fixes: ad3c7b18c5b3 ("arm: use swiotlb for bounce buffering on LPAE configs")
