Ard Biesheuvel 07c707858d ArmPkg/ArmDmaLib: use the cache writeback granularity for alignment
When allocating memory to perform non-coherent DMA, use the cache
writeback granule rather than the data cache linesize for alignment.
This prevents the explicit cache maintenance from corrupting
unrelated adjacent data if the cache writeback granule exceeds
the cache linesize.
