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.
