When rtasd receives a PRRN event, it needs to make a series of RTAS
calls (ibm,update-nodes and ibm,update-properties) to retrieve the
updated device tree information. These calls are already handled in the
pseries_devtree_update() routine used in partition migration.

This patch simply exposes pseries_devicetree_update() so it can be
called by rtasd. pseries_devicetree_update() and supporting functions
are also modified to take a 32-bit 'scope' parameter. This parameter is
required by the ibm,update-nodes/ibm,update-properties RTAS calls, and
the appropriate value is contained within the RTAS event for PRRN
notifications. In pseries_devicetree_update() it was previously
hard-coded to 1, the scope value for partition migration.

Patch looks fine, so:

However, you could usefully put some of the description from your 0/11
email into this patch description, since the 0/11 email doesn't get
preserved in git.
