Convert the last users (mostly in ASoC) to use dma_request_chan() and
drop deprecated dma_request_slave_channel() completely.

I think the best is to allow Mark to take the whole lot and provide an
immutable tag or branch to others (DMAengine and GPIB).

Changelog v2:
- Add a comment that errors are now propagated to the caller (Frank)
- Make sure the error pointer is not dereferenced (Sashiko, Mark)
- Collected tags

v1: <20260915100931.3593242-1-andriy.shevchenko@linux.intel.com>

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
