Extend charge state machine to accommodate Kirby
Currently only x86 platform uses charge_state.c, and it's been tailored
to fit smart battery and bq247xx charger family.
For Kirby, we have different types of battery and charger, and thus need
to make some change to accommodate them. This includes:
- Abstract out smart battery specific bit mask
- Implement missing functions required by GAIA chipset module
- Add config flags for charging-enabled GPIO pin
- Allow battery that doesn't report desired voltage and current
BUG=chrome-os-partner:22055
TEST=Build all boards
TEST=Boot Link and check it charges/discharges battery
TEST=Test charging/discharging on Kirby along with the next two CLs
BRANCH=None
