Subject: [PATCH] powerpc: Add AT_HWCAP2 to indicate V.CRYPTO category support

The Vector Crypto category instructions are supported by current POWER8
chips, advertise them to userspace using a specific bit to properly
differentiate with chips of the same architecture level that might not
have them.
