Correct the json keyword

Keyword "bind" has been changed to "devAddress"
as some of the files like gpioMonitor uses "devAddress" to get the
device address and use it for binding/unbinding.
Also, we use this address for binding/unbinding both, so devAddress
would be appropriate name for the keyword.
