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 at 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'
