rapidio: run discovery as an asynchronous process
Modify mport initialization routine to run the RapidIO discovery process asynchronously. This allows to have an arbitrary order of enumerating and discovering ports in systems with multiple RapidIO controllers without creating a deadlock situation if enumerator port is registered after a discovering one. Making netID matching to mportID ensures consistent net ID assignment in multiport RapidIO systems with asynchronous discovery process (global counter implementation is affected by race between threads).
