mb/google/kahlee/variants/baseboard: Set STAPM percentage

Default STAPM percentage is 68%, which causes a lot of thermal throttling.
AMD experimented with 80%, it works for grunt. This is initial code to
provide easy change path for other grunt based platforms.

BUG=b:111608748
TEST=build and boot grunt.
