dmatest: convert to dma_request_channel
Replace the client registration infrastructure with a custom loop to
poll for channels. Once dma_request_channel returns NULL stop asking
for channels. A userspace side effect of this change if that loading
the dmatest module before loading a dma driver will result in no
channels being found, previously dmatest would get a callback. To
facilitate testing in the built-in case dmatest_init is marked as a
late_initcall. Another side effect is that channels under test can not
be used for any other purpose.
