jhibbits 083d0f1bd4 Remove a singleton in the DPAA driver, to allow multiple fman instances
Some devices (P5040, P4080) have multiple frame managers in their DPAA
subsystems.  This was prevented by use of a softc singleton in the DPAA
driver.  Since if_dtsec(4) has moved to be a child of fman, it can access
the fman device data via the parent object.
