Series bus: fsl-mc: Make remove function return void |

  The error message emitted in fsl_mc_driver_remove() is very generic.
Replace it by a message that mentions the reason for the failure.

Returning zero instead of a negative value has no side effect apart from
suppressing the generic error message.

The first if condition in dprc_remove() can never be true, as this would
prevent successful probing of the device and then .remove wasn't called.
So this can just be dropped.
