Subject: cell: allow linux to map Cell regs on legacy SLOF tree.
From: Jean-Christophe DUBOIS <jcd@xxxxxxxxxxxxxxx>
The platforms missing the "cpus" property in the "be" node are mono-Cell
platforms such as CAB or Getaway.
Therefore it is possible to assume that if there is no "cpus" properties under
the "be" node then we can safely return the "device node" without more
checking. This is a bit hacky but ... it allows it to work on these
platforms.
