The 'struct ethosu_device' has been passed as argument to classes.
This creates a circular dependency dependency and it gives all
classes full visibility to all resources in the device struct. This
patch removes the circular dependency.
Using device_lock() and device_unlock() to for synchronization.

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.

pass no resources to the firmware and can be cancelled without
resetting the firmware.
