The x86 busdma subsystem allows using multiple implementations. By default the classic bounce buffer approach is used, however on systems with IOMMU it could be in runtime switched to more efficient hardware accelerated implementation. This commit adds ARM64 port of the x86 busdma framework and bounce buffer backend. It is ready to use on IO coherent systems. If the IO coherency cannot be guaranteed, the cache management operations have to be added to this code in places marked by /* XXX ARM64TODO (...) */ comments. Also IOMMU support might be added by registering another busdma implementation like it is already done on the x86.
