rapidio: add handling of redundant routes
Detects RIO link to the already enumerated device and properly sets links
between device objects. Changes to the enumeration/discovery logic:
1. Use Master Enable bit to signal end of the enumeration - agents may
start their discovery process as soon as they see this bit set
(Component Tag register was used before for this purpose).
2. Enumerator sets Component Tag (!= 0) immediately during device
setup. This allows to identify the device if the redundant route
exists in a RIO system.
