dt-bindings: dma: Update ADMA bindings for tegra264

- Update ADMA device tree bindings for tegra264 to support up to 64
  interrupt channels by setting 'interrupts' property maxItems to 64.
- Also, update the 'allOf' conditional schema to ensure correct maxItems
  for 'interrupts' based on compatible string, including tegra210 (22)
  and tegra186 (32) ADMA controllers.
