Updated ARL_PMT_DMU_GUID value. Arrow Lake PMT DMU GUID has
been updated after it was released. This updates ensures that
the die c6 value is available in the debug filesystem.
Fixes: 83f168a1a437 ("platform/x86/intel/pmc: Add Arrow Lake S support to intel_pmc_core driver")

Tested this on my Lenovo P1 G8 and confirmed that it fixed the error message that was seen previously.
