util: Remove the subfunc arg from M5OP_FOREACH.

Now that the annotation pseudo ops are removed, the subfunction is
always zero. It is no longer decoded within gem5 either. The format of
the pseudo op func/subfunc mechanism is unchanged for compatibility, but
the subfunc field will always be zero now.
