Cortex-A57/A72: 1742098: ELR recorded incorrectly on interrupt taken between cryptographic instructions in a sequence

This option removes the AES hwcap for aarch32 user-space to
workaround erratum 1742098 on Cortex-A57 and Cortex-A72.

Affected parts may corrupt the AES state if an interrupt is
taken between a pair of AES instructions. These instructions
are only present if the cryptography extensions are present.
All software should have a fallback implementation for CPUs
that don't implement the cryptography extensions.

If unsure, say Y.
