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.
