Subject: [PATCH 1/6] bus: fsl-mc: Only warn once about errors on device unbind

If a platform driver's remove function returns an error code, this
results in a (generic and little helpful) error message. Otherwise the
value is ignored.

As fsl_mc_driver_remove() already emit an error message, return 0 also
in the error case. The only effect is to suppress the device core's
error message.
