As discussed on the topic of shmobile DMA today, jz4740 is the only
user of the slave_id field in dma_slave_config besides shmobile. This

dmaengine API, so we should get rid of it.
Do you have a link to that discussion?

I'm really not comfortable with this patch, since it is a step back. But I
guess the end justify the means. So if it helps to get rid of slave_id I'm
ok with it, sooner or later jz4740 will be converted to DT so once that's
done the filter function can be removed again. But please put the filter
function in a non arch specific header so we can still compile test things.
And maybe note in the commit message that this is meant as a temporary hack.
