mb/google/poppy/variants/nocturne: Tune DPTF settings for CPU
Update CPU passive temperature threshold value from 70C to 80C, to avoid early throttling for spiky workloads. Also, change CPU throttling interval from 1 sec to 5 sec for CPU temperature. BUG=b:116400298 BRANCH=None TEST=Manual performance testing on nocturne.
