powerpc/pseries: Call ibm,os-term if the ibm,extended-os-term is present

We have had issues in the past with ibm,os-term initiating shutdown of a
partition. This is confusing to the user, especially if panic_timeout is
non zero.

The temporary fix was to avoid calling ibm,os-term if a panic_timeout was set
and since we set it on every boot we basically never call ibm,os-term.

An extended version of ibm,os-term has since been implemented which gives us
the behaviour we want:

  "When the platform supports extended ibm,os-term behavior, the return to the
  RTAS will always occur unless there is a kernel assisted dump active as
  initiated by an ibm,configure-kernel-dump call."

This patch checks for the ibm,extended-os-term property and calls ibm,os-term
if it exists.
