[PATCH v3 11/12] Enable PRRN Event handling

The Linux kernel and platform firmware negotiate their mutual support
of the PRRN option via the ibm,client-architecture-support interface.
This patch simply sets the appropriate fields in the client architecture
vector to indicate Linux support and will cause the firmware to begin
sending PRRN events via the RTAS event-scan mechanism.
