Fix dma nvic issues on dual core lines

This commit addresses #3256 by disabling dma NVIC interrupt enablement at startup.
Instead, per-channel NVIC interrupt enablement is now done with the rest of the dma channel configuration.
This ensures that each core will only handle the interrupts of the DMA channels that it uses.
