i2c: imx: Add timer for handling the stop condition
Most IMX I2C interfaces don't generate an interrupt on a stop condition, so it won't generate a timely stop event on a slave mode transfer. Some users, like IPMB, need a timely stop event to work properly. So, add a timer and add the proper handling to generate a stop event in slave mode if the interface goes idle.
