i2c: imx: make bitrate an u32 type

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.
