补充信息
1）drv提供的日志注册接口 int32_t drv_log_set_module_log_level(int32_t level, int32_t *module_ids, int32_t size）；
2）解注册流程也需要补充一下，drv的解注册函数在plog里面有实现，urma的解注册接口是urma_unregister_log_func
另外需要考虑一下设置日志级别为null（4）的情况
这里有一份示例代码，仅供参考

实测还发现一个现象，设置级别会触发三次dlog_drv.c:230的打印，看一下是不是有冗余注册的问题，以及维测打印是不是不够明确

还有一个测试例失败了，之前做过一个动态库构造函数里懒启动的，要求PlogFlush不在构造函数里启动，分析一下失败原因，是不是因为dlopen后驱动打印日志导致的
plog_mdc场景下出现同一个进程两次注册、两次解注册的流程，是不是因为同时加载slog和alog导致的

Thanks for sending an requirement! Please fill in the following template to help quickly solve your problem.
Backgroud（背景信息）
功能要求：
1）日志级别发生变化时，log支持将日志级别设置给drv
2）device侧实现与host归一，log支持将日志输出函数注册给drv
Origin（信息来源）
URMA团队
Benefit / Necessity （价值/作用）
urma日志对接到slog日志
Design（设计方案）
UB日志级别定义
typedef enum urma_vlog_level
{
URMA_VLOG_LEVEL_EMERG = 0,
URMA_VLOG_LEVEL_ALERT = 1,
URMA_VLOG_LEVEL_CRIT = 2,
URMA_VLOG_LEVEL_ERR = 3,
URMA_VLOG_LEVEL_WARNING = 4,
URMA_VLOG_LEVEL_NOTICE = 5,
URMA_VLOG_LEVEL_INFO = 6,
URMA_VLOG_LEVEL_DEBUG = 7,
URMA_VLOG_LEVEL_MAX = 8,
urma_vlog_level_t;
日志封装接口伪码：
static int ub2alog_level[8]={3, 3, 3, 3, 2, 1, 1, 0}
void reportUBlog(int level, char *msg){
alogRecord(UB, DLOG_TYPE_DEBUG, ub2alog_level[level], msg);
}
UB的设置日志级别接口为：
void urma_log_set_level(urma_vlog_level_t level); drv需要提供日志级别设置接口给alog，当alog初始化从环境变量读取到日志级别或者应用调用了alog的日志级别设置接口后，alog会调用drv的日志级别设置接口。 drv完成级别的转换后，设置给UB。urma日志注册接口：
urma_status_t urma_register_log_func(urma_log_cb_t func);
依赖关系：
写日志函数注册：log注册给drv函数func1，drv注册给urma函数func2
写日志数据流：urma调用func2传入level和内容，func2内会做级别转换，然后调用func1
设置日志级别：用户调用设置日志级别的接口设置log的日志级别，log会调用drv的接口设置level，需要区分模块（当前只有DRV和URMA，因此需要新增URMA模块枚举）
本issue只关注log跟drv的交互，drv和URMA的交互由其他issue跟踪。
log当前已有部分逻辑，在PlogRegisterDriverLog内注册，但是只在host侧生效，现在需要在device侧也实现类似的逻辑；并将功能做增强
驱动级别设置接口名和参数尚未最终确定，当前初步定为 void halSetLevel(int level, int *modArray, int modNum); 如果设置DRV和URMA的级别一致，可以通过一个数组传入两个模块的module id
