This driver decouples the LCD interface from the target-specific LCD parameters. It makes it possible to reuse most of the ipod6g driver code on ipodnano3g and ipodnano4g. No difference in the produced binaries for ipodnano2g (normal and bootloader). Tested on ipod6g (normal and bootloader). This is a part of the large iPod Nano 3G and iPod Nano 4G support patch.
