Modify code for sensor reading

[Yi-Shum]

Hi @DelphineChiu,

We want to modify the code for sensor reading, including:

1. The member init_args in struct sensor_cfg should only be used in the function DeviceName_init().
   So we want to add a private data member that will be used in other functions such as DeviceName_read().
2. Add the header files for each sensor.
3. Changed ADC amplification calculation from arg0 and arg1 to post_sensor_read_hook and post_sensor_read_args.

Do you have any suggestions for this?

Thanks,
Yi-Shum

Hi @Yi-Shum

Meta and we plan to have main_v2 ready on 3/31.
Would you pls check main_v2 on #189 and provide the optimization based on main_v2?
