[PATCH] PPC4xx: Add support for multiple I2C busses
This patch adds support for multiple I2C busses on the PPC4xx
platforms. Define CONFIG_I2C_MULTI_BUS in the board config file
to make use of this feature.
It also merges the 405 and 440 i2c header files into one common
file 4xx_i2c.h.
Also the 4xx i2c reset procedure is reworked since I experienced
some problems with the first access on the 440SPe Katmai board.
