i2c-imx: add gpio recovery functionality
If the I2C is disturbed by other signals sometimes the i2c-imx bus gets stuck
with SDA being low.
This adds a recovery function to the bus driver.
When e.g. a device driver detects a stuck bus
int i2c_recover_bus(struct i2c_adapter *adap)
can be called to try to recover the bus.
