[Fix]
cherry picked from linux-firmware commit 348d8a97 ("i915: Add DMC v2.01 for
ADL-S").
[Test]
Verified on Intel SDP
[Where problems could occur]
It's a new firmware for new GPU, not possible to introduce regressions.
[Other Info]
Impish has this already. And while ADL-S support begins since v5.13, only
focal (for oem-5.13) will be nominated.
