ARM: pxa: add the zylonite board

Add the first pxa3xx board, zylonite. Zylonite is the Marvell System
Development Platform.

Several version are available, based on either :
 - PXA300
 - PXA310
 - PXA320

This version was only tested on a PXA310 based board, and uses :
 - the ethernet controller
 - the nand controller

These drivers seem to be common to all zylonite boards.
