Flush spl image after loading into memory in case d-cache is enabled.
Signed-off-by: York Sun york.sun@nxp.com --- Not sure if anyone noticed that SPL loads image but it doesn't flush the cache. As far as MMU/cache stays the same, we don't notice it. Shall we flush it?
This patch is only tested on limited platforms.
