scsi: ufs: Convert all platform drivers to return void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning) and this typically results in resource leaks. To
improve here there is a quest to make the remove callback return void. In
the first step of this quest all drivers are converted to .remove_new()
which already returns void. Eventually after all drivers are converted,
.remove_new() is renamed to .remove().
All platform drivers below drivers/ufs/ unconditionally return zero in
their remove callback and so can be converted trivially to the variant
returning void.
