[rdma-core] debian: Whitelist coherent DMA supporting architectures

Commit Message

Benjamin Drung April 30, 2018, 5 p.m. UTC

rdma-core defines `udma_to_device_barrier`, `udma_from_device_barrier`,
and `mmio_flush_writes` in `util/udma_barrier.h` for architectures that
support coherent DMA. Instead of blacklisting the unsupported
architectures, use an explicit whitelist. This will disable coherent DMA
support for riscv64 (RISC-V 64 bits little-endian).

Closes: #894995
