Input: amimouse - 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/input/mouse/amimouse: section mismatch in reference: amimouse_driver+0x8 (section: .data) -> amimouse_remove (section: .exit.text) that triggers on an allmodconfig W=1 build.
