nuc: Add i2cscan and kbpress commands for FAFT.
Add i2cscan and kbpress commands for FAFT.
Remove unnecessary i2c reading since there is no race condition.
Bugs fixed:
Fixed i2c_read_string bug since we shouldn't enable NACK if flag doesn't
contain I2C_XFER_STOP.
Fixed i2c_unwedge bug since the parameter should be port not controller.
Fixed state machine bug since we should restore bus state back to idle
if bus encountered timeout.
Modified drivers:
1. board.h: Add i2cscan and kbpress commands for FAFT.
2. i2c.c: Remove unnecessary reading since there is no race condition.
3. i2c.c: Fixed i2c_read_string and i2c_unwedge bugs.
4. i2c.c: Restore to idle state if bus encountered timeout.
5. board.h: Add CONFIG_LOW_POWER_IDLE for better power consumption.
