[stm32][pandora] fix the static conflict error in ROMFS

2023-06-20T04:22:52Z

#### 为什么提交这份PR (why to submit this PR) 原版编译报错：Static declaration of 'romfs_root' follows non-static declaration in dfs_romfs.h 原因为：在`board/ports/drv_filesystem.c`71行用`static`定义了常量`romfs_root`，而在`rt-thread/components/dfs/dfs_v1/filesystems/romfs/dfs_romfs.h`29行，有它的外部引用： ``` extern const struct romfs_dirent romfs_root; ``` Original compilation error: Static declaration of 'romfs_ root' follows non-static declaration in dfs_romfs. h The reason is: in 'board/ports/drv_filesystem.c' line 71 use `static` define `romfs_root`, while in `rt-thread/components/dfs/dfs_v1/filesystems/romfs/dfs_romfs.h` line 29, with its external reference: ``` extern const struct romfs_dirent romfs_root; ``` #### 你的解决方案是什么 (what is your solution) 在`drv_filesystem.c`中，不可以用static修饰这个常量，故去掉`static`关键字。 In `board/ports/drv_filesystem.c`, it is not allowed to define this constant with static, so the `static` keyword must be removed. #### 在什么测试环境下测试通过 (what is the test environment) 正点原子潘多拉开发板 stm32l475-atk-pandora
