drivers: sensor: Add suport for TMAG5170 3D Hall sensor

Browse source 
Introduce support for Texas Instruments TMAG5170
high-precision linear 3D Hall-effect SPI sensor.
This driver allows to configure measurements on
magnetic and temperature channels. It is also
possible to read rotation of the magnet.
