software node: Constify node_group in registration functions

Browse Source 
The software_node_register_node_group() and
software_node_unregister_node_group() functions take in essence an
array of pointers to software_node structs. Since the functions do not
modify the array declare the argument as constant, so that static
arrays can be declared as const and annotated as __initconst.
