Using an arbitrary string as a printf-style format can be a security
problem if that string contains % characters, as the optionalal
-Wformat-security flag points out:
drivers/dma/dmaengine.c: In function '__dma_async_device_channel_register':
drivers/dma/dmaengine.c:1073:17: error: format not a string literal and no format arguments [-Werror=format-security]
1073 | dev_set_name(&chan->dev->device, name);
| ^~~~~~~~~~~~
Change this newly added instance to use "%s" as the format instead to
pass the actual name.

Document the IPG and AHB clocks that are needed by the DMA hardware
as required properties.
It is not possible to have DMA functional without the DMA clocks
being turned on.
