BugLink: https://bugs.launchpad.net/bugs/1869235


ECC RAM is not supported for some families of AMD Ryzen 3rd gen CPUs in
kernel 5.3


Supports are added in kernel 5.4. The actual fix is e53a3b267f but
3e443eb353 contains the required PCI IDs.


Verified on ASRockRack X470D4U2-2T as discussion on LP:1869235

[Regression Potential]

Low. They are cherry-picked from upstream kernel which has them since
kernel 5.4.
