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.

Description is inaccurate. It's either combined or per-channel IRQs.
