Subject: [PATCH v2] bus: fsl-mc: constify the struct device_type usage
Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move all the
device_type variables used in the bus to be constant structures as well,
placing it into read-only memory which can not be modified at runtime.
