Upstream has added an "enhancement" to the DMA allocator to
reject coherent allocations less than a a full page, so allocate
device managed memory instead of artificially inflating the
buffer sizes. This has the added benefit of having this memory
automatically freed when the module is unloaded, avoiding
possible leaks.
