Lars-Peter Clausen 17a993032b util_dac_unpack: Make number of channels and channel width configurable
Always using 128bit for the input word unnecessarily increases the DMA
alignment requirements. This breaks existing software which assumes that the
DMA alignment requirement is 64bit.

So make it configurable whether we want 8 or 4 channels and while we are at
it also make the channel width configurable.

Lars-Peter Clausen 6ad589475a up_axi: Prevent read and write requests from racing against each other
Make sure that if a read and a write request arrive on the very same clock
cycle to only accept one of them. The simple solution chosen here is to only
accept the write request when this happens and delay the acceptance of the
read request until the write request is finished.

This solution is not fair since a write request will always take precedence,
which in theory allows the write bus to starve the read bus. But in practice
we should never see that many write requests that we are unable to answer
the read request.

Lars-Peter Clausen dc7b3e085c axi_dmac: Fix issues with non 64-bit AXI masters
Make sure that the address generator behaves correctly when the buswidth is not
64-bit. Also since the source and destination can have different widths add
separate parameters for source and destination address alignment.

Lars-Peter Clausen 36ef882da0 axi_dmac: data_mover: Improve timing
We do not know which 'last' condition to use before hand, but we can pre-compute
the result for both conditions and then use them. This removes the comparison
from the already pretty long combinatorial path.

Also simplify a few expressions.
