[PATCH][AArch64] Remove crypto extension from default for cortex-a53, cortex-a57

[Kyrill Tkachov]

Hi all,

Some configurations of Cortex-A53 and Cortex-A57 don't ship with crypto,
so enabling it by default for -mcpu=cortex-a53 and cortex-a57 is 
inappropriate.

Tested aarch64-none-elf. Reminder that at the moment all the crypto
extension does is enable the use of the ACLE crypto intrinsics in arm_neon.h

Ok for trunk?

Thanks,
Kyrill
