mb/google/poppy/variants/atlas: Update DPTF parameters
Reduce the CPU passive threshold sample rate from 5 seconds to 1 second so DPTF will react faster to rapid temperature increases. Signed-off-by: Todd Broch <tbroch@chromium.org> BUG=b:113101335 BRANCH=atlas TEST=manual performance/power testing on nocturne. No longer see messages like below in syslog, 'CPU0: Package temperature above threshold' Change-Id: I2dc9d157b54500bae29e123978bb8ad6e05ef619 Reviewed-on: https://review.coreboot.org/28325 Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Sumeet R Pawnikar <sumeet.r.pawnikar@intel.com> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
