parport: Save a few bytes of memory

Most of parport_register_dev_model() callers pass a 'name' that is a
constant string.

So kstrdup_const() can be used to save the duplication of this string
when it is not needed. This saves a few bytes of memory.

Use kfree_const() accordingly when this string is freed.
