dt-bindings: interrupt-controller: aspeed,ast2700: Correct #interrupt-cells and interrupts count

Browse source

Update the AST2700 interrupt controller binding to match the actual
hardware and the irq-aspeed-intc driver behavior.

 - Interrupts:

    First-level INTC banks request multiple interrupt lines to the root
    GIC, with a maximum of 10 per bank. Second-level INTC banks request
    only one interrupt line to their parent INTC-IC. Therefore, set the
    interrupts property to allow a minimum of 1 and a maximum of 10
    entries.

 - #interrupt-cells:

    Set '#interrupt-cells' to <1> since the aspeed intc driver does not
    support specifying a trigger type; only the interrupt index is used.
