powerpc: Add AT_HWCAP2 to indicate V.CRYPTO category support
commit dd58a092c4202f2bd490adab7285b3ff77f8e467 upstream.
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.
