Unlike the raw/ioat driver, this dmadev driver does not have a private APIs
so I'm not sure it needs the EXPERIMENTAL tag on it.
I will update this in v5.

I'm not sure about merging two driver additions into a single release note
entry - one for the doc maintainers and tree committers to comment on.
Rather than "IOAT devices" I think the official name of the hardware should
be used, and you probably should add "respectively" at the end of the first
sentence to make it clear (once you change the name) which hardware is used
by which driver.
I will separate them into 2 entries and reword in v5.
Thanks,
Conor.
