[PATCH v5 3/5] lib: utils/irqchip: Add compatible string for Andestech NCEPLIC100

Add compatible string for Andestech NCEPLIC100 found on Renesas RZ/Five SoC
which is equipped with AX45MP AndesCore.

While at it drop the comma after the sentinel as it does not make sense to
have a comma after a sentinel, as any new elements must be added before the
sentinel.

dts example (Single-core AX45MP):

    soc: soc {
          ....
          plic: interrupt-controller at 12c00000 {
              compatible = "renesas,r9a07g043-plic", "andestech,nceplic100";
              #interrupt-cells = <2>;
              #address-cells = <0>;
              riscv,ndev = <511>;
              interrupt-controller;
              reg = <0x0 0x12c00000 0 0x400000>;
              clocks = <&cpg CPG_MOD R9A07G043_NCEPLIC_ACLK>;
              power-domains = <&cpg>;
              resets = <&cpg R9A07G043_NCEPLIC_ARESETN>;
              interrupts-extended = <&cpu0_intc 11 &cpu0_intc 9>;
          };
          ....
    };
