Hello all,

Thank you for your review. I have revised v1 driver. Please give your feedback at that time.

This driver supports:
- Event: rising and falling proximity events.
- Reading channels through read_raw_callback.

v2 changed below:
- Add a new entry in alphabetical order at Kconfig.
- Use #define register and commands.
- Use CM36651_* prefix.
- Use i2c_smbus_* APIs.
- Fixed cm36651_read_output() function.
- Code cleanup
