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.

========== original bug report ==========

Dell reported sporadically hang up at its desktop (Intel based platform + AMD Navi3.x dGPU) during warm boot stress test.

After updating DMCUB firmware version to 0x07002600, they observed a significant improvement in passing rate. And Dell wants to add the updated DMCUB firmware (ver 0x7002600) to its OEM image.

DMCUB firmware (ver 0x7002600) is at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/amdgpu/dcn_3_2_0_dmcub.bin?id=bd2ad5e65d3bc38fc35eed8c3dbb5e40ae45df20.
