arm: Uniquely name imx25 I2C buses.

The imx25 chip provides 3 i2c buses, but they have all been named
"i2c", which makes it difficult to predict which bus a device will
be connected to when specified on the command line.

This patch addresses the issue by naming the buses uniquely:
  i2c-bus.0 i2c-bus.1 i2c-bus.2
