media: software_node: unregister software_nodes in reverse order

 * software_node_unregister_node_group - Unregister a group of software nodes

 * @node_group: NULL terminated array of software node pointers to be unregistered

 *

 * Unregister multiple software nodes at once.

 * Unregister multiple software nodes at once. The array will be unwound in

 * reverse order (i.e. last entry first) and thus if any members of the array are

 * children of another member then the children must appear later in the list such

 * that they are unregistered first.
