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