DMA Enabler

Can I have 2 DMA enablers in my driver? I have a device capable of making
DMA transfers from different HW, and the capabilites based on the HW it is
transferring from is different.

ie. I plan on using one withWdfDmaProfilePacket64 and the other with
WdfDmaProfileScatterGather64. Are there any restrictions?

Yes if these are two independent DMA engines then it makes sense to have to
separate DMA enablers.
