Use ids for identifying messages sent to EthosU firmware
Avoid to use pointers to kernel memory as identify messages, prior this
change, if memory is reused that can lead to unexpected conflicts.
Remove ref counting from capabilities and network_info since memory is
freed in only one place.
Finally, extract the capabilities code in its own files.
