MIPS: OCTEON: reintroduce crypto features check
Reintroduce run-time check for crypto features. The old one was deleted because it was unreliable, now decide the crypto availability on early boot when the model string is constructed. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
