ide: Adds wwn=hex qdev option

Browse source 
Allow the user to specify a disk's World Wide Name.

Linux guests can address disks by their unique World Wide Name number
(e.g. /dev/disk/by-id/wwn-0x5001517959123522). This patch adds support
for assigning a World Wide Name number to a virtual IDE disk.
