[PATCH v2 1/7] powerpc: Add new HWCAP bits

[Alistair Popple]

POWER10 introduces two new architectural features - ISAv3.1 and matrix
multiply accumulate (MMA) instructions. Userspace detects the presence
of these features via two HWCAP bits introduced in this patch. These
bits have been agreed to by the compiler and binutils team.
