[PATCH 18/18 v2] powerpc: Update arch vector to indicate support for CMO

[Robert Jennings]

From: Nathan Fontenot <nfont at austin.ibm.com>

Update the architecture vector to indicate that Cooperative Memory
Overcommitment is supported.

This is the last patch in the series.  Committing it will signal to 
the platform firmware is CMO enabled.
