I2C bus 0 was not initialized correctly. There is an offset between i2c
index and the structure number of pad info. So i2c bus 0 can be in an
inconsistent state.
This problem become visible on B{4,6}50v3 with the CPUC HW watchdog enabled.
Sometimes when the CPUC HW watchdog interrupted the boot process, U-Boot was
not able to read VPD from I2C/EEPROM and the system failed to boot up again,
because a device connected to that bus was stuck in data transfer state (from
previous boot attempt) and there was no method to recover (struct
mxc_i2c_bus::idle_bus_fn was not set) courtesy of incorrect initialization.
