mb/google/poppy/variants/nocturne: Update DPTF settings
The previous does not work well enough when testing with
high ambient temperature. Update DPTF settings to make
it work better.
List of tweaks:
1. Raise DRAM Critical temperature from 48C to 55C
Note that there are mechanisms in EC that complement
this because of DPTF limitation that we can't have
multiple passive temperatures.
2. Lower response time for DRAM temp sensor from 60s to 5s.
3. Increase throttle priority to the charger when DRAM hit
passive temperature from 100 to 200.
BUG=b:112550414
BRANCH=None
TEST=Manually tested by thermal team.
