Merge in files from Allwinners lichee BSP tarball

The Pine64 Wiki[1] links to a BSP tarball, among other things
containing a dump of an ARM Trusted Firmware source tree with
Allwinner changes on top.
Since the tarball does not contain any version history information
about the changes, this commit is just the diff between the ATF 1.0
release and the files from the Allwinner provided tarball.
The executable flag from many source has been removed.
