[Impact]

It shows the firmware is missing, and runtime power management has been
disabled:

  i915 0000:00:02.0: [drm] Failed to load DMC firmware
  i915/adlp_dmc_ver2_10.bin. Disabling runtime power management.

[Fix]

Upstream commit 3d32f216 ("i915: Add ADL-P DMC Support").

[Test Case]

Verified on Intel ADL-M/ADL-P RVPs.

[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-P/M support begins since v5.14,
only focal (for oem-5.14) is being nominated.

v2: correct subject only
