Save and check device id for acc and gyro calibration parameters.

Fix config utility to work with all devices of each type.
Accel, gyro and mag devices correctly set their device_id devtype.
Combo devices (mpu6000 lsm303d) now correctly return their devtype.
config util shows device id for all sensor types.
Add, save during calibration and check during preflight ID parameters for accelerometer and gyro
