mb/google/eve: Update DPTF parameters 

1) Set the critical temperature threshold to 100C to match changes
on other boards.  This is intended to reduce DPTF-initiated thermal
shutdowns before it has had a chance to react.

2) Reduce the CPU passive threshold sample rate from 5 seconds to 1
second so DPTF will react faster to rapid temperature increases.

BUG=b:67459049
BRANCH=eve
TEST=manual performance/power testing on Eve hardware
