sparse found this assignment of u32 to an int. Fix it:
drivers/i2c/busses/i2c-imx.c:540:56: warning: incorrect type in argument 3 (different signedness)
and also fix the type in platform_data. All current users use values
which fit into the old and new type, so it is a safe change.

Changes since V1: also change type in platform_data. Thanks to Richard.
