[PATCH] rio: Use discovered bit to test if enumeration is complete

[Liu Gang <b34182@freescale.com>]

The discovered bit in PGCCSR register indicates if the device has
been discovered by system host. In Rapidio system, some agent devices
can also be master devices. They can issue requests into the system.
