RISC-V: Support non-coherent DMA operations
** Do not upstream **
This is hacky fix just for testing. The actual patch would read the
RISCV_UNCACHED_OFFSET from the DT for only the non-coherent devices.
All other devices on beagleV and all other platform should just set
dma_default_coherent to true.
[Emil: remove spurious whitespace and fix format string warning]
