mmc: dw_mmc: hi3789cv200: Obviously always return success in remove c…

…allback

dw_mci_pltfm_remove() 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.
