cmd: spl: provide address and size of prepared FDT in environment
Writing prepared FDT to persistent storage should be possible in scripts. Create environment variables containing address and size of the updated FDT. Scripts can use these variables after running 'spl export fdt ...' command to write the new blob to persistent storage. Signed-off-by: Anatolij Gustschin <agust@denx.de>
