powerpc: Update AT_HWCAP[2] bits
Linux commit ID a4700a26107241cc7b9ac8528b2c6714ff99983d reserved 2 more bits for the instructions darn (Deliver a Random Number) and scv (System Call Vectored). Linux commit ID 6997e57d693b07289694239e52a10d2f02c3a46f reserved another bit for internal usage. * sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_DARN and PPC_FEATURE2_SCV. * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add scv and darn.
