i2c: get battery information from charge state
ARM systems currently use SBS kernel driver which talks to the battery
through I2C passthu in the EC. Instead when asking for battery
information try getting it from the charge state machine first, and
then try the battery if charge state does not have the information.
This reduces latency by cutting out the battery response time.
