fbdev: Remove support for Carillo Ranch driver
As far as anybody can tell, this product never shipped. If it did, it shipped in 2007 and nobody has access to one any more. Remove the fbdev driver and the backlight driver. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Signed-off-by: Helge Deller <deller@gmx.de>
