dt-bindings: interrupt-controller: loongson,liointc: Fix dtbs_check warning for reg-names
As we know, the Loongson-2K0500 is a single-core CPU, and the core1-
related register (isr1) does not exist. So "reg" and "reg-names" should
be set to "minItems 2"(main nad isr0).
This fixes dtbs_check warning:
DTC_CHK arch/loongarch/boot/dts/loongson-2k0500-ref.dtb
arch/loongarch/boot/dts/loongson-2k0500-ref.dtb: interrupt-controller@1fe11400: reg-names: ['main', 'isr0'] is too short
