Rong Chang ee495ac6a6 Add stm32 I2C master driver ...

A polling mode I2C master driver. Interfaces for read/write byte
and word are implemented. i2c_read_string() is currently an empty
function.

CONFIG_SMART_BATTERY added to daisy board for testing.

Move smart_battery.o back to CONFIG_SMART_BATTERY since it is not
depended on charging state machine.
