Subject: swiotlb-xen cleanups v4

Hi Xen maintainers and friends,

please take a look at this series that cleans up the parts of swiotlb-xen
that deal with non-coherent caches.


Changes since v3:
 - don't use dma_direct_alloc on x86

Changes since v2:
 - further dma_cache_maint improvements
 - split the previous patch 1 into 3 patches

Changes since v1:
 - rewrite dma_cache_maint to be much simpler
 - improve various comments and commit logs
 - remove page-coherent.h entirely
