fs: Move ls and read methods into ext4, fat
It doesn't make a lot of sense to have these methods in fs.c. They are filesystem-specific, not generic code. Add each to the relevant filesystem and remove the associated #ifdefs in fs.c. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
