Both cortex-a53 and cortex-a57 can be configured without crypto
support. The behavior of -mcpu=cortex-a5[37] should be to assume the
presence of crypto, we will need to add support for -mcpu=core+feature
in the future in order to provide a mechanism to turn off crypto.
I think this patch is OK and should go in now.
