拉取/合并请求描述:(PR description)

[
添加HC32F460系列的wdt的外设驱动;

  1. HC32F460有两个看门狗SWDT和WDT,这里添加WDT驱动,软件启动;
  2. WDT使用的是系统时钟PCLK3,精度高;
  3. WDT是16位递减计数器,计数值只能选择:256、4096、16384、65536这几种,不能任意设置。时钟分频可选 :4、64、128、256、512、1024、2048、8192。鉴于这种情况,看门狗的复位时间只能是几个固定的数值,无法设置任意时间。本次PR驱动为固定数值2.6s(16384计数值,8192分频)。
    3.该PR已在 ev_hc32f460_lqfp100_v2开发板测试通过,测试启动看门狗设备,在main中添加while(1);死循环,程序约2s多复位一次。
