feat(ansible): update 1n-tx2 config
Arm VPP Device requires newer drivers, otherwise we're frequently seeing
a deadlock when running csit-initialize-vfs.
We've observed server slowdown in VPP Device jobs in the past and
testing revealed that disabling the cppc_cpufreq seemingly resolves the
issue (there was no observed slowdown with a sample of 500 job runs).
Also update Nomad config (server IPs).
