Hello all,

Thank you for your advices. I have revised some minor issues of v4 revision.

This patch is the fifth revision for Capella CM36651 proximity and RGB light sensor driver. The driver exposes five channnels: Red, Green, Clear and proximity.
It also support detection proximity event.

This dricer supports:
- Event: rising and falling proximity events.
- Reading channel through read_raw callback.
- Writing sensor data integration time each channel through write_raw callback.

v5 changed below:
- Use *_REG_NUM macro at size of array.
- Revise error handling in probe function.
