The edma controller support optional error interrupt, so update interrupts
and interrupt-names's maxItems.

This seems like something were you would know based on the soc (or
compatible) whether or not 64 or 65 is the correct maximum for that
device?

Not exactly, 64 channel is maxium value, which IP supportted. There are
difference instances in the same SOC. Some may only 31 dma channel, some
may only 12, some have 64. Each channel have one irqs and one shared err
irq.

Ideally it should be property 'dma-channels' + 1. But not sure if schema
can check such case.
