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.
I will change it to: interrupts: description: | If the IP-core synthesis parameter DMAX_INTR_IO_TYPE is set to 1, this will be per-channel interrupts. Otherwise, this is a single combined IRQ for all channels. minItems: 1 maxItems: 8
How's that sound?
