The result of this looks good, but I fear that changing the filter function
like this wil break all drivers that currently use the plat-samsung/dma-ops.c
code. For migration purposes, I think the best way is to change
samsung_dmadev_request() to match the new filter_param format.

After that is done, you can migrate all the drivers using samsung_dma_get_ops
over to the new dma_request_slave_channel interface without breaking
anything when only part of the series is applied.
