Yu Chien Peter Lin 127a3f2ab4 platform: andes/ae350: Use fdt irqchip driver 
Andes PLIC is compatible with plic driver. The PLIC base address and
number of source can be obtained by parsing the device tree.

Yu Chien Peter Lin 8234fc1bdf lib: utils/reset: Add Andes fdt reset driver support 
Add ATCWDT200 as reset device of AE350 platform, this driver requires
SMU to program the reset vector registers before triggering WDT software
restart signal.

dts example:

  smu@f0100000 {
    compatible = "andestech,atcsmu";
    reg = <0x00000000 0xf0100000 0x00000000 0x00001000>;
  };

  wdt: wdt@f0500000 {
    compatible = "andestech,atcwdt200";
    reg = <0x00000000 0xf0500000 0x00000000 0x00001000>;
    interrupts = <3 4>;
    interrupt-parent = <&plic0>;
    clock-frequency = <15000000>;
  };

Yu Chien Peter Lin ef9f02e7fb lib: utils/timer: Add Andes fdt timer support 
Since we can get the PLMT base address and timer frequency from
device tree, move plmt timer device to fdt timer framework.

dts example (Quad-core AX45MP):

  cpus {
      ...
      timebase-frequency = <0x3938700>;
      ...
  }
  soc {
      ...
      plmt0@e6000000 {
          compatible = "andestech,plmt0";
          reg = <0x00 0xe6000000 0x00 0x100000>;
          interrupts-extended = <&cpu0_intc 0x07
                                 &cpu1_intc 0x07
                                 &cpu2_intc 0x07
                                 &cpu3_intc 0x07>;
      };
      ...

Yu Chien Peter Lin 88f58a3694 platform: andes/ae350: Use fdt serial driver 
Andes UART is compatible with uart8250 driver. We can use
fdt_serial_init() as platform console init hook.

  serial0: serial@f0300000 {
    compatible = "andestech,uart16550", "ns16550a";
    reg = <0x00000000 0xf0300000 0x00000000 0x00001000>;
