Subject: [PATCH v3 1/2] dt-bindings: hwmon: (lm75) Add AMS AS6200 temperature sensor

as6200 is a temperature sensor with a range between -40°C to
125°C degrees and an accuracy of ±0.4°C degree between 0
and 65°C and ±1°C for the other ranges.

Signed-off-by: Abdel Alkuor <alkuor@...il.com>

Changes in v3:
  - Enable interrupt property conditionally based on the chips that
    support it.
  - Fix alignment for the added example
Changes in v2:
  - Incorporate as6200 into lm75 bindings
