i2c: 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
i2c_adapter_type and i2c_client_type variables to be constant structures as
well, placing it into read-only memory which can not be modified at
runtime.
