mmc: sdhci-of-arasan: Obviously always return success in remove callback

sdhci_pltfm_unregister() returns 0 unconditionally and returning an
error in a platform remove callback isn't very sensible. (The only
effect of the latter is that the device core emits a generic warning and
then removes the device anyhow.)

So return 0 unconditionally to make it obvious there is no error
forwarded to the upper layers.

This is a preparation for making platform remove callbacks return void.
