[PATCH] Input: amimouse - Mark driver struct with __refdata to prevent section mismatch

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

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.
