[Michael Reed]

From: Michael Reed <Michael.Reed at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/2077861

SRU Justification:

[Impact]
Add Arrow Lake-U/H SoC compute die IDs for EDAC support.


[Test Plan]

[Fix]
According to https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=88150cd9501b9498e377cc4440325267c6921f90, Intel Arrow Lake IBECC(In-Band ECC)) feature is already added in upstream.
