The of_find_matching_node() function returns NULL on error, it never
returns error pointers. This doesn't really impact runtime very much
because if "syscon" is NULL then syscon_node_to_regmap() will return
-EINVAL. The only runtime difference is that now it returns -ENODEV.

The first patch which added this file doesn't give a good hint what the
subsystem prefix should be so I just guessed "bus: arm-integrator-lm:".
