When specifying ide devices using -device, the cmos information which the bios depends on is not written. This patch generalizes the cmos hd data setting for the existing code path and adds the ability to call that code on a per machine, per ide drive basis. This is important for older guests, such as Windows XP, and Windows Server 2003. I needed to add an id to the IDEBus structure since there wasn't a way to identify whether an ide bus was primary or secondary in the lower level code.
