[PATCH] rapidio: fix multi-switch enumeration
This patch contains two fixes for RapisIO enumeration logic:
1. Fix enumeration in configurations with multiple switches. The patch adds:
a. Enumeration of an empty switch. Empty switch is a switch that
does not have any endpoint devices attached to it (except host device
or previous switch in a chain). New code assigns a phony destination
ID associated with the switch and sets up corresponding routes.
b. Adds a second pass to the enumeration to setup routes to
devices discovered after switch was scanned.
2. Fix enumeration failure when riohdid parameter has non-zero value.
Current version fails to setup response path to the host when it has
destination ID other that 0.
