Davinci platforms may define a default queue for each channel controller. If one is not defined, the default queue is set to EVENTQ_1. However, there's no way to distinguish between an unset default queue to one that is set to EVENTQ_0, as EVENTQ_0 = 0.
In order to keep existing behaviour on platforms which don't specify a default_queue member, the default_queue member was modified to be a pointer to enum dma_event_q. A NULL value means that this member was not specified.
Mmm, perhaps it's better to drop the default EVENTQ_1 concept and explicitly initilaize that field for every SoC. It's also possible to offset the event queue number by 1. I don't like the pointer solution.
