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.
