feat(drivers/pmic): 添加IP5306硬件看门狗功能支持

Browse Source 
为IP5306 PMIC驱动添加了硬件看门狗脉冲生成功能，通过RTC2、GPIOTE和PPI外设实现硬
件级的唤醒脉冲生成。当配置keepalive-hardware属性时，系统将使用硬件方式而非软件
定时器来产生看门狗脉冲。

在设备树中新增keepalive-hardware布尔属性，用于启用硬件看门狗功能，并相应更新了
驱动程序以支持软硬件两种看门狗模式的选择。

相关的DTS文件和配置也进行了相应调整，包括添加必要的nRF52硬件抽象层依赖以及
RTC2和GPIOTE相关配置选项。
