sparc: remove sparc64/sparcv9 code
The sparc64/sparcv9 code is incomplete. Furthermore there is no real embedded hardware for sparc64 available, so better remove it until someone comes up with a complete port. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
