Bug description:
[Impact]
The error is shown in dmesg:
kernel: intel_pmc_core INT33A1:00: pmc_core: couldn't get DMU telem endpoint -6
c6 status is not shown in debugfs.

[Fix]
Add Arrow Lake PMU GUIDs in pmc_core:
a32f7d76e3cd7 platform/x86:intel/pmc: Add DMU GUID to Arrow Lake U/H
3b603955f2423 platform/x86:intel/pmc: Add support for multiple DMU GUIDs
644ab3bc98ee3 platform/x86:intel/pmc: Update Arrow Lake telemetry GUID

[Test]
The pmc error is not shown in dmesg.
# cat /sys/kernel/debug/pmc_core/die_c6_us_show
16476381

[Where problems could occur]
It may break intel pmc support.

Noble 6.8 kernel got some conflicts and need many commits and revert.
So SRU for questing, oem-6.17 and resolute.
