Why you do not add the `interrupt` for the it?
the gpmi-nand needs to parse the interrupt out.

The non-dt way also does not have interrupt resource for dma device.
It seems the channel interrupt resource is handled in each client device.
I'm not familiar with gpmi-nand, but I guess you may need to handle
it in gpmi driver, just like mxs-mmc driver.
