The link support is no longer limited to the pseudo file system and now covers both soft (symbolic) links and hard links across the VFS. Rename the configuration option PSEUDOFS_SOFTLINKS to the more accurate FS_LINKS and update all references in the source, headers, Kconfig, documentation and board defconfigs accordingly. This is a configuration rename; any out-of-tree defconfig that still selects PSEUDOFS_SOFTLINKS must be updated to FS_LINKS. Signed-off-by: zhengyu16 <zhengyu16@xiaomi.com>
