Kill bogus #if 0'd stuff for interrupts. They don't happen, and this

driver will need more serious help to work with an interrupt driven
path.  There's many subtleties in driving the DMA engine with
interrupts in many configurations.  Best to not "guess" what the right
way would be and mislead people.
