When a DMA channel is opened the IRQ should not get activated
automatically, this allows it to pull data out manually without the help
of interrupts. This is needed for a workaround in the vrx200 Ethernet
driver.

If you'd like this to go via the netdev tree to keep it with the rest of
the series:

Thanks, I also prefer that this goes through netdev.

Though I'd be happier if we didn't have DMA code seemingly used only by
an ethernet driver in arch/mips/ :)

There are also some out of tree driver that use this DMA code. This
should probably be converted to a DMA channel driver but that is not
very high on my todo list.
