Break circulare dependency on struct ethosu_device
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.
