google/chell: Set DPTF critical temperature to 99C 

If we boot without a heatsink then DPTF may power off the system when
it starts if the CPU temp is >90C.  Since TJmax is 100C set the
critical threshold to just below that value.

Also remove the active thresholds as chell does not have a fan.
This will have DPTF use the default values but without the DPTF active
policy it shouldn't get used.

BUG=chrome-os-partner:46694
BRANCH=none
TEST=build and boot on chell w/o a heatsink
