[PATCH] dt-bindings: interrupt-controller: loongson,liointc: Fix warnings about reg and interrupt description

[Binbin Zhou]

As we know, some Loongson-2K CPUs are single-core, e.g. Loongson-2K0500,
and the "isr1" means routing interrupts to core1, which should be
optional. So add maxItems/minItems limits to reg/reg-names.
Also, The interrupt-names attribute represents a list of parent
interrupt names that should change with interrupts.
