feat(drivers): 添加IP5306 PMIC驱动支持
- 添加IP5306 PMIC驱动实现，包括I2C通信和GPIO唤醒功能 - 实现电源管理芯片的状态读取接口（充电状态、满电状态） - 集成Wakeup保持脉冲功能，支持可配置的脉冲宽度和间隔时间 - 添加设备树绑定文件和Kconfig配置选项 refactor(blinky): 集成IP5306电源管理芯片到电池模块 - 在电池模块中集成IP5306 PMIC状态监控功能 - 修改日志输出格式，显示电池电压及充电/满电状态 - 增加设备初始化检查和错误处理机制 - 配置电源管理限制级别为暂停模式 build: 配置CMakeLists.txt以包含驱动子目录 - 更新主CMakeLists.txt文件添加drivers子目录 - 配置驱动程序的构建层次结构（pmic -> ip5306） - 设置条件编译目标源文件 docs: 添加设备树和板级配置支持 - 添加mini_keyboard板的I2C引脚控制配置 - 配置IP5306设备节点和相关GPIO引脚定义 - 启用I2C配置选项以支持PMIC通信
