but includes debugging to ensure that the reg being submitted is the
one that follows in the packet. Convert most uses of OUT_RING to it,
and convert a couple of OUT_REG sets to DMA_PACKET0/OUT_RING_REG. Also,
add checking to see if more registers are submitted to a DMA_PACKET0
than should be, to avoid hangs during stupid mistakes (checking for
less isn't done).
