xorg-server: Xorg won't allow to have more than one isolateDevice

Description
Bug reported on the Debian BTS by Maximiliano Curia:
Using isolateDevice limits the video cards that X will touch when doing a pci analysis. This allows to have different X servers in different video cards, that's mostly used for multiseat. I wanted to have a Xinerama X (with two video cards) and a secondary seat X. But isolateDevice would not allow to "isolate" two video cards, so the Xinerama+multiseat was imposible.
The patch attached changes the xf86IsolateDevice to list of PCIids so it's possible to have more than one isolated device per X server.
