The 83xx controller has external start capability, but lacks external pause
capability. Hook up the external start function pointer for the 83xx
controller.

Though there is no way to enable external start in the mainline driver,
the DMA_SLAVE patch I posted last week does give the ability to enable
external start.
I have tested this patch along with the DMA_SLAVE patch using a driver
for some custom hardware that uses the external DMA control lines.
