[PATCH v3 2/5] dt-bindings: hwmon: Add possible new properties to max31827 bindings

[Daniel Matyas <daniel.matyas@xxxxxxxxxx>]

These modify the corresponding bits in the configuration register.

adi,comp-int is a hardware property, because it affects the behavior
of the interrupt signal and whatever it is connected to.

adi,timeout-enable is a hardware property, because it affects i2c
bus operation.

v2 -> v3: Changed commit subject and message

v1 -> v2: Added adi,timeout-enable property to binding. Fixed
dt_binding_check errors.
