scsi: core: Constify the struct device_type usage

Browse Source 
Since commit aed65af1cc ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
scsi_host_type, scsi_target_type and scsi_dev_type variables to be constant
structures as well, placing it into read-only memory which can not be
modified at runtime.
