Initial commit for device N90 by Sanei
Finish the renaming from zatab to n90.

The template's initialisation script missed some of these, which leads to
interesting problems when you try to actually build it (it *mostly* works!).
Modules for the N90's touchscreen and analogue switch chip.

(The second might not be needed; I've not had it apart to check whether it's
actually present or not.)
ui_menu_level isn't accessible any more.
sun4i-crane-defconfig looks right for this board.

In fact, given that the image it came with had the device name as
"crane-anpei", it's quite possible that "crane" might be a sensible name for
this family of devices.
Accept more device names when installing this image.
