ppc4xx: Switch to I2C bus numer 0 for chip_config command
All currently available 4xx derivats have the I2C bootstrap EEPROM located on I2C bus number 0. This patch now first sets this bus number, so that the chip_config command also works for board with multiple I2C busses, like Katmai. Signed-off-by: Stefan Roese <sr@denx.de>
