[PATCH 2/2] MCI: init device_node for MCI mainarea cdev

[Lucas Stach]

This fixes a regression, where boards specifying the environment
path using the form device-path = &phandle, "partname:part" would
be unable to find their env.

This is due to of_find_path() switching to cdev_by_device_node()
internally, which expects the device_node member of the main
area cdev to be initialized.
