[CRYPTO] sha512: Rename sha512 to sha512_generic
Rename sha512 to sha512_generic and add a MODULE_ALIAS for sha512 so all sha512 implementations can be loaded automatically. Keep the broken tabs so git recognizes this as a rename. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
