dt-bindings: dma: snps,dw-axi-dmac: constrain the items of resets for JH7110 dma

The DMA controller needs two reset items to work properly on JH7110 SoC,
so there is need to constrain the items' value to 2, other platforms
have 1 reset item at most.

dt-bindings: dma: dw-axi-dmac: extend the number of interrupts

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.
