Bug description:
[SRU Justification]
[Impact]
Devices hang up at its desktop (Intel based platform + AMD Navi3.x
dGPU) during warm boot stress test.
[Fix]
AMD GPU dcn firmware upgrade to upstream commit bd2ad5e6 needed. The
affected blob is amdgpu/dcn_3_2_0_dmcub.bin, which has stayed the
first revision since Jammy is ever released. However, the related
commits from the upgrade path have also included blob updates to all
kinds of different, unrelated hardware models.
This pull request bumps only the affected binary to the target commit
per online discussion with AMD.
[Test Case]
Perform checkbox warmboot stress test:
$ checkbox-cli run com.canonical.certification::stress/reboot
[Where problems could occur]
While DCN blob maybe shared with several hardware models, with
confirmation from IHV, there should be little risk to upgrade it.
[Other Info]
Affects both Jammy and Mantic.
