[PATCH v3 2/6] dt-bindings: hwmon: Move LM63 family to a dedicated binding

Move the National Semiconductor LM63, LM64, and LM96163 compatibles out
of trivial-devices.yaml and into a dedicated binding. Describe their
integrated fan control and preserve the optional interrupt used by the
ALERT output. Permit use as thermal cooling devices via #cooling-cells.

+description: |
+  The LM63 family provides local and remote temperature monitoring together
+  with fan speed monitoring and PWM fan control. Supported devices include
+  the National Semiconductor LM63, LM64 and LM96163.
