deploy check for pmu_name fails for alderlake cpus #173
Description
Here's my result of running make deploy:
TASK [intellabs.kafl.kernel : Checking that pmu_name is not broadwell] *********

In fact there are two paths:
/sys/devices/cpu_atom/caps/pmu_name
/sys/devices/cpu_core/caps/pmu_name
Both contain "alderlake_hybrid". The CPU is Core i9-13900K
Temporary workaround: delete respective check in the file deploy/intellabs/kafl/roles/kernel/tasks/pre_tasks.yml.
