From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Since at least the 2.05 architecture, the slbia instruction takes an
IH field in the opcode to provide some control on the effect of the
slbia on the ERATs (level-1 TLB).

We can safely ignore it as we always flush the whole qemu TLB but
we should allow the bits in the decode.
