net: dsa: 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 the dsa_type
variable to be a constant structure as well, placing it into read-only
memory which can not be modified at runtime.
