The Canaan k210 apparently has a Sysnopsys Designware AXI DMA controller, but according to the documentation & devicetree it has 6 interrupts rather than the standard one. Support the 6 interrupt configuration by unconditionally extending the binding to a maximum of 8 per-channel interrupts thereby matching the number of possible channels.

rob asked you to drop this in last patch, pls fix that and send with his ack
If the IP-core synthesis parameter DMAX_INTR_IO_TYPE is set to 1, thiswill be per-channel interrupts. Otherwise, this is a single combined IRQfor all channels.minItems: 1
