iio: proximity: Add driver support for TYHX's HX9023S capacitive proximity sensor

Browse Source 
A SAR sensor from NanjingTianyihexin Electronics Ltd.

The device has the following entry points:

Usual frequency:
- sampling_frequency

Instant reading of current values for different sensors:
- in_proximity0_raw
- in_proximity1_raw
- in_proximity2_raw
- in_proximity3_raw
- in_proximity4_raw
and associated events in events/
