parport: amiga: Mark driver struct with __refdata to prevent section mismatch

As described in the added code comment, a reference to .exit.text is ok
for drivers registered via module_platform_driver_probe(). Make this
explicit to prevent the following section mismatch warning

	WARNING: modpost: drivers/parport/parport_amiga: section mismatch in reference: amiga_parallel_driver+0x8 (section: .data) -> amiga_parallel_remove (section: .exit.text)

that triggers on an allmodconfig W=1 build.
