EM/Battery: Enable temperature based charging use case on clovertrail.
BZ: 34235
This patch adds temprature based charging and extreme charging
use-cases. As part of the patch following has been added:
1. existing worker thread bq24192_maintenance_worker, tempearture
based charging capability
2. SFI table parsing for battery properties
3. Extreme charging capability via sysfs interface
4. Temperature reading capability via ADC
