The DMA API requires that 32-bit DMA masks are always supported, but on
arm LPAE configs they do not currently work when memory is present
above 4GB. Wire up the swiotlb code like for all other architectures
to provide the bounce buffering in that case.

Hi Russell,
This series adds swiotlb support to the 32-bit arm port to ensure
platforms with LPAE support can support DMA mapping for all devices
using 32-bit dma masks, just like we do on other ports that support

Check that the pfn returned from arch_dma_coherent_to_pfn refers to
a valid page and reject the mmap / get_sgtable requests otherwise.
Based on the arm implementation of the mmap and get_sgtable methods.
