Is i2c-mpc built into your kernel? It's not going to module auto-load
because the names don't match - fsl-i2c and i2c-mpc.

It is built into the kernel.

Put a printk in it's init function to make sure it is initializing.

Next thing I do is put printks over in arch/powerpc/.. to tell me
which strings from the device tree are being looked for.

You can also look in /proc/device_tree and make sure fsl-i2c is in there.

When you find the problem is will probably be something simple like a
mismatch between _ and -. I have been down this path before and spent
a day figuring out why a module wouldn't load and it was a simple
typo.

But a message on init and make sure it is loading.
static int __init fsl_i2c_init(void)
{
      int rv;

      rv = of_register_platform_driver(&mpc_i2c_driver);
      if (rv)
              printk(KERN_ERR DRV_NAME
                     " of_register_platform_driver failed (%i)\n", rv);
      return rv;
}
