[POWERPC] Add null pointer check to of_find_property
Update function of_find_property() to return NULL if the device_node
passed to it is also NULL. Otherwise, passing NULL will cause a null
pointer dereference.
Without this, the legacy_serial driver will crash if there's no
'chosen' node in the device tree.
