Subject: [PATCH] dmaengine: idxd: Move DSA/IAA device IDs to IDXD driver

Since the DSA/IAA device IDs are only used by the IDXD driver, there is
no need to define them as public IDs. Move their definitions to the IDXD
driver to limit their scope. This change helps reduce unnecessary
exposure of the device IDs in the global space, making the codebase
cleaner and better encapsulated.

There is no functional change.

Fixes: 4fecf944c051 ("dmaengine: idxd: Add new DSA and IAA device IDs for Diamond Rapids platform")
Fixes: f91f2a9879cc ("dmaengine: idxd: Add a new DSA device ID for Granite Rapids-D platform")
