dma-mapping fixes for 5.3-rc

Two fixes for regressions in this merge window:

 - select the Kconfig symbols for the noncoherent dma arch helpers
   on arm if swiotlb is selected, not just for LPAE to not break then
   Xen build, that uses swiotlb indirectly through swiotlb-xen
 - fix the page allocator fallback in dma_alloc_contiguous if the CMA
   allocation fails

----------------------------------------------------------------

      arm: select the dma-noncoherent symbols for all swiotlb builds
