driver: soc: xilinx: Convert to platform remove callback returning 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 only effect compared to returning
zero is that the core emits an error message. By converting to
.remove_new() (which is semantically equivalent to return 0 in
.remove()) this error message is suppressed which is a good thing as
xlnx_event_manager_remove() already emits an better error message.
