Frostflow: Implement LED behavior for RSOC
The EC modifies the raw battery level to a 'Display'
level that is then sent to the AP.
Battery Display 0-94%:Amber
Battery Low Display 0-10%
The Display values map to raw values as:
Display Raw
10 13
11 14
94 91
95 92
BUG=b:258153920
BRANCH=none
TEST=zmake build frostflow
