[U-Boot] [PATCH 1/2] 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.

Applied to u-boot-ppc4xx/next. Thanks.
Cheers, Stefan
