[Fix]
The upstream PR added missing ID for the platforms.
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/16320/
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/17569/
After creating the test build to include the PR above, ODM verified
passed on those platform.
[Test case]
Install fixed package on the systems, check that display works.
[Where things could go wrong]
Although one commit drops a couple of pci-id's, they were already dropped
from the jammy kernel for lp1990242
