rambi: Move the CPU passive/critical threshold config to DPTF

Browse source 
The rest of the thermal configuration is in DPTF ACPI code so
move the CPU settings there as well.

Also remove the unused thermal.asl file.

BUG=chrome-os-partner:17279
BRANCH=baytrail
TEST=build and boot on rambi, start DPTF application
