Eric Anholt 5ca5fe7111 Add an OUT_RING_REG macro for use with DMA_PACKET0, which is like OUT_RING ...

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).
