Group soc specific data in a global struct instead of repeating it for each call to imxXX_add_flexcanX. The structs holding the actual data are placed in .init.constdata and so don't do much harm. Compared to the previous approach this reduces code size to call imx_add_flexcan. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
