nhk8815: remove platform.S, which was unused at link time
This source file, which I got by the vendor in their own port, was not actually executing because lib-based compilation didn't call lowlevel_init (we have CONFIG_SKIP_LOWLEVEL_INIT). With the change to object-based linking, an undefined symbol in this file started hitting in the final link.
