[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.
