[Impact]
The error is shown in dmesg:

c6 status is not shown in debugfs.

Add Arrow Lake PMU GUIDs in pmc_core:

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
