[SRU][PULL][linux-firmware][Jammy] amdgpu: Update DMCUB for DCN314 & Yellow Carp

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/2029384

[Impact]

Monitors black out when an external one connects via thunderbolt3 on AMD Ryzen
9 PRO 7940HS w/ Radeon 780M Graphics.

[Fix]

This can be fixed by upstream linux-firmware commit 253cc179d849 ("amdgpu:
Update DMCUB for DCN314 & Yellow Carp").

However, in linux-firmware/lunar and jammy, the commit history related to the
files to be updated often associated with many other more, they're now updated
with overwrites without cherry-pick ancestor commits along the history.

For linux-firmware/mantic, a simple cherry-pick would do.

[Test Case]

Connect an tbt3 featured external monitor (ASUS PA27AC) after boot to GUI.
Check if both the built-in and external monitors lights up as usual.

[Where problems could occur]

Update amdgpu firmware are error prone, verified on targeting series as
possible.

[Other Info]

While this affects linux-oem-6.1/jammy, as well as linux/lunar kernels, Jammy
and Lunar are nominated for fix.
