In the future, the /rtas/ibm,termno device node is going away, to be
replaced with /vdevice/vty nodes. This patch is the minimum necessary
to boot relying on the vty nodes, falling back to "ibm,termno" if
necessary on older systems.

Note that hvc_count will need to be replaced, as we can have multiple
vty nodes containing discontiguous vterm numbers (as opposed to
"ibm,termno", which only expresses vterm numbers as "base, total

At the moment, firmware is supporting the old "ibm,termno" interface as
well as vty nodes, but that is expected to change.

Attached are both 2.4 and 2.5 patches. If there are no comments, these
will be going in soon...
