[Impact]
Products with DCN 3.5.1 need linux-firmware to be added for noble. Matching kernel support is already in kernel 6.9.

Without this firmware amdgpu won't bind.

[Test Plan]
Boot system and ensure accelerated graphics works.

[Where problems could occur]
This firmware is only loaded on hardware with DCN 3.5.1, VPE 6.1.1, VCN 4.0.6, SDMA 6.1.1, GC 11.5.1, PSP 14.0.1, or ISP 4.1.1
