nds32 is one of the only architectures which still have a reset_cpu() implementation that makes use of the `addr` parameter. The rest of U-Boot now ignores it and passes 0 everywhere. It turns out that even here, reset_cpu() is no longer referenced anywhere; reset is either not implemented (e.g. ae3xx) or realized using a WDT (e.g. ag101).
Remove this left-over implementation in preparation for the removal of the `addr` parameter in the entire tree.
