[PATCH 24.11] dma/idxd: add device ids for new HW versions

[PATCH 24.11] dma/idxd: add device ids for new HW versions

[Bruce Richardson]

Add in two extra PCI device id's for future HW versions to be
supported by idxd driver. This aligns with the definitions present
in kernel idxd driver [1].

This is a backport of main tree patch[1], which hopefully can be
considered for backport to 24.11, since it only contains a couple
of new device IDs, and no functional changes.

LGTM. I added the main branch commit id to the commit message and queued
for push to 24.11 branch.
