The ext4 implementation has been taken from U-Boot with some
changes:
- No global variables to allow for multiple filesystems to
be mounted and multiple files to be open.
- remove fs internal link following and use the barebox link
implementation.
- remove write support. This is incomplete in U-Boot, so I decided
to skip this for now.
