dt-bindings: hwmon: Add possible new properties to max31827 bindings
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.
