ipq806x: do not allocate coherent memory in dma engine hotpath
The available amount of coherent DMA memory is very limited. On Linux
4.4 this issue was worked around by increasing the pool size.
It turns out that using coherent memory here is completely unnecessary.
This change reworks the driver code to use kzalloc+dma_map_single
instead.
