Set the Wolf thermal table.(Wolf branch only)
This is hard code for wolf. (code base from CL Falco: set fan/thermal
steps (BRANCH ONLY) )
The thermal table for wolf is
Step Fan RPM trigger point (CPU Tj) unit K / 'C
Step 1 0 under 318K / 45'C
Step 2 3000 318K / 45'C
Step 3 3500 323K / 50'C
Step 4 4000 328K / 55'C
Step 5 4200 332K / 59'C
Step 6 4500 335K / 62'C
Step 7 4800 338K / 65'C
Step 8 5000 341K / 68'C
368K / 100C => assert PROCHOT
373K / 105C => give the CPU three second to cool off, then shutdown
378K / 110C => shutdown immediately
BUG=none
BRANCH=wolf ONLY!
TEST=manual
