[POWERPC] Update documentation for of_find_node_by_type()
The documentation for of_find_node_by_type() incorrectly refers to the "name" parameter - it should be "type". Also the behaviour when from == NULL is not really documented, fix that. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
