dmaengine: idxd: Add new DSA and IAA device IDs for Diamond Rapids platform

A new DSA device ID, 0x1212, and a new IAA device ID, 0x1216, are
introduced for Diamond Rapids platform. Add the device IDs to the IDXD
driver.

The name "IAA" is used in new code instead of the old name "IAX".
However, the "IAX" naming (e.g., IDXD_TYPE_IAX) is retained for legacy
code compatibility.
