低版本内核defconfig移植到高版本，发现删除了大量驱动配置项，这种情况最好留意一下是不是它们配置项改名了，还是得把正确的名字加回来

关键摘要:

• 移除了多个配置选项，可能影响系统功能和性能。需要确认这些选项的移除是否符合项目需求和设计规范。
• 注释掉了 CONFIG_IO_STRICT_DEVMEM 配置选项，需要评估是否有必要这样做，因为这可能会影响系统的内存管理策略。
• 添加了 # CONFIG_STRICT_DEVMEM is not set 注释，需要确保这一改动不会影响系统配置的完整性。

是否建议立即修改:

• 是，需要确保这些更改不会对系统功能和性能产生负面影响，并且与项目的整体设计和需求相符。同时，应该验证 # CONFIG_STRICT_DEVMEM is not set 注释的必要性。
