Initialize the ofw_bus_devinfo on the portals to prevent a crash.

Browse Source 
If the device tree doesn't contain a cpu-handle field in any bman-portal or
qman-portal, it will exit without setting up the devinfo, leaving it
uninitialized.  This will lead to attempts to free random memory, and ultimately
panic.
