[PATCH] mcb: constify the struct device_type usage

[Ricardo B. Marliere]

Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
mcb_carrier_device_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
