powerpc: Fix fallout from device_node->name constification
Commit c22618a1, "drivers/of: Constify device_node->name and
->path_component_name" changes device_node name to a const value, but
the PowerPC scom code still assigns it to a non-void field in
debugfs_blob_wrapper. The /right/ solution might be to change the
debugfs_blob_wrapper->data to also be const, but that is a bit
risky. Instead, cast the value to (void*). It is a bit ugly, but it
is the safest change until it can be investigated where
debugfs_blob_wrapper can be modified.
