From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

This prepares of_device_id.data becoming const. Without this change the
following warning would occur:

	drivers/tty/serial/imx.c: In function 'serial_imx_probe_dt':
	drivers/tty/serial/imx.c:1430:17: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]
