I found a way to do it. This implies to:
- register the i2c-imx driver at the postcore initcall level.
- register the board i2c bus at the postcore initcall level
  and perform the rest of the board initialization.

The i2c-imx driver is shared between architectures. If you do not
foresee any side-effects on the ARM architecture and this is acceptable
to you, I would like to submit a patch including this solution.

Otherwise, I would prefer to keep the current implementation.
