hwmon: (lm70) Add ti,tmp125 support
The TMP125 is a 2 degree Celsius accurate Digital
Temperature Sensor with a SPI interface.
The temperature register is a 16-bit, read-only register.
The MSB (Bit 15) is a leading zero and never set. Bits 14
to 5 are the 1+9 temperature data bits in a two's
complement format. Bits 4 to 0 are useless copies of
Bit 5 value and therefore ignored.
This was tested on a Aerohive HiveAP-350.
Bonus: lm70 supports TMP122/TMP124 as well.
I added them to the Kconfig module description.
