878f27e552 fs: Use an empty string for the root directory 
It is easier to use an empty string when the root directory is intended.
Adjust the code to drop use of "/" and NULL and just use and empty
string.

ab25244811 fs: Add support for a file 
Directories can have a number of files within them. U-Boot only needs to
create a file object for those that have been opened for read/write. Add
the concept of a file, with its directory as parent.

4ae46c7db4 fs: Add support for a directory 
Filesystems can have a number of directories within them. U-Boot only
worries about directories that have been accessed. Add the concept of
a directory, with the filesystem as parent.

Note that this is not a hierarchical device structure, so UCLASS_DIR
devices always have a UCLASS_FS as the parent.
