Peppy: set fan/thermal steps (BRANCH ONLY)
NOTE: This CL is for the branch only. It does NOT go into ToT.
This sets the thermal steps and fan speeds as requested:
Step Fan RPM trigger point (CPU Tj) unit K / 'C
Step 1 0 under 320K / 47'C
Step 2 3200 320K / 47'C
Step 3 3700 330K / 57'C
Step 4 4000 337K / 64'C
Step 5 4400 344K / 71'C
Step 6 4900 351K / 78'C
Step 7 5500 358K / 85'C
Step 8 6500 368K / 95'C
This also sets the CPU hot points to the following:
373K / 100C => assert PROCHOT
378K / 105C => give the CPU three second to cool off, then shutdown
383K / 110C => shutdown immediately
BUG=chrome-os-partner:21971
BRANCH=peppy ONLY! Not ToT!
TEST=manual
