mb/google/brya/var/kinox: Set power limit based on charger type 

Set different power limit values using host command to detect charger
type from ec.

Scenario:
1. With 90W customized adapter, set to baseline.
2. With 170W customized adapter, set to performance.
3. With above 90W barrel jack/type-c adapter, set to performance.
4. With below 90W barrel jack/type-c adapter, set to baseline.

BUG=b:231911918
TEST=Build and boot to Chrome OS
