crypto: curve25519 - do not pollute dispatcher based on assembler
Since we're doing a static inline dispatch here, we normally branch based on whether or not there's an arch implementation. That would have been fine in general, except the crypto Makefile prior used to turn things off -- despite the Kconfig -- resulting in us needing to also hard code various assembler things into the dispatcher too. The horror! Now that the assembler config options are done by Kconfig, we can get rid of the inconsistency. Signed-off-by: Jason A.
