ppc4xx: Switch to I2C bus numer 0 for chip_config command

Browse Source 
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.
